Molar Volume Lab Report

2. Obtained a 2-3 cm strip of magnesium metal ribbon and coiled it loosely into a small ball. Added the magnesium metal to the acid in the test tube.

In the ADI Molarity Lab, the primary tasks was to use different values of moles of solute, volume of solvent, and molarity to find the mathematical relationships between them. To find these relationships, our group had to change the quantities of each of the variables and visually observe the molarity within the solution. For instance when using Cobalt (II) Nitrate to find the relationship between volume of the solution and the molarity of the solution; the group kept the amount of moles of the solute at a constant of 1.00 moles because if it would have changed it would have caused inaccurate data. We first set the volume of the solution to 0.2 liters. The molarity of the solution was 5.00 mol/L. Then we changed the volume of the solution

It should be noted that not all supplies are listed here as exactly what is needed to perform each method but a complete list can be found in the lab manual preceding each experiment.

The mole is equivalent to 6.022 X 10²³, which indicates how much particles of element is in one gram. The molar mass can be found in the atomic mass from the periodic table. The Lab 11 involves how much oxygen (O) magnesium (Mg) combines through combustion and form Magnesium Oxide. The magnesium strip of unknown mass was used as main ingredient for experiment. The lab also requires crucible with cover, crucible tongs, ring pad, and Bunsen burner.

The type of measurement that I was able to record with the most number of significant figures was the mass. To measure this, I used an electric scale which showed up the the 0.001 place, and when objects were placed on it, it showed at least 4 significant figures. The exactness of these measurements mean that they were precise.

The concept investigated in this lab was the relationship between absorbance and concentration, or molarity. This relates to the guiding question, “How could you make 1 liter of Pirate Purple #2 dye?”, because in order to create more dye, you must obtain an equation from the graph to calculate the amount, in grams, of blue and red dye that must be mixed to create the certain shade of purple. The molarity of a substance is the amount of moles per one liter of liquid that it contains. A solution is a mixture that contains two or more substances. A solute is one substance that is dissolved in another substance, while a solvent is the matter that the solute is dissolved in. When plotted on a graph, absorbance and concentration (molarity) have a

DESIGN Gravity makes objects fall down. In this experiment, with the help of gravity, water was poured down a conical beaker with different volume values and the time taken for all the water to empty the conical beaker was measured. In this experiment, the time measurements using Tracker software was stopped after the water reached the cylindrical part of the glass funnel. Research Question: How is the time taken for water to empty the conical glass funnel dependent on the volume of water? Independent Variable: Volume of water Dependent Variable: Time taken for water to empty the conical glass funnel except the cylindrical part of the glass funnel.

Set up support stand with support ring and wire gauze for the purpose of heating water. Fill 400 mL beaker half way with tap water. Place it on the wire gauze over the burner. While it heats, weigh your dry test tube with a cor to 0.01g and record. Fill the test tube and metal in the beaker of water and it it boil. The Cork is used

The following procedure must be repeated twice as there has to be two trials. At the end the average of the formulas will be determined. Before beginning the experiment it is important to dawn safety gear including gloves, apron and goggles. We will first obtain the mass of an empty weigh boat and record the mass in the data table. When using the analytical balance it is important to zero the scale by closing the doors of the balance and pressing the zero button. Place 3-4 pieces of magnesium metal on the weigh boat and record the mass in the data table. Grab the 2 test tubes and label them according to the trial. Then place the 2 test tubes into the 400-ml beaker. Using the 10-ml graduated cylinder measure out 8.0-ml of 6M HCl and then pour

For this experiment you will need four jars, four different liquids, a timer, a measuring beaker, making tape, marker, pen and pencil for notes. Get four

After the presoaking process, each tubing was opened and one side of the tubing was folded and tied with either string or dental floss. Using a graduated cylinder the bags was filled with its corresponding solutes. The first bag was filled with 10mL of dH2O, bag two was filled with 10mL of 15% sucrose, bag three was filled with 10mL of 30% sucrose and the fourth bag was filled with 10mL of dH2O. After each bag was filled, the other side of the bag was folded and tied off with string or dental floss. Afterward each bag was individually weighed for the initial mass of the experiment and recorded into a table. Acquiring four cylinder beakers, beakers one, two, and three were filled with 200mL of dH2O while the fourth beaker was filled with a 30% sucrose solution.

The first expiriment for my volume project was determing the volume of a solid. For this expiriment I used a metric ruler and a small block of wood. I began with recording the measurements of my piece of wood. The width was 10.3cm, the length was 17.5cm, and the height was 1.4cm. My next step was multiplyig all of my measurements together to find the volume and after doing so, I got 252.35cm3.

Twist and fold one end of the 15-cm copper wire and insert the magnesium ribbon through it. Bend the magnesium ribbon around the copper wire to

This experiment is primarily focused on the measurement of the density and the determination of the partial molar volume of ethanol-water system. A partial molar volume is a thermodynamic quantity defined as a change in volume per mole of substance added to the mixture at constant temperature and pressure, indicating that molar volumes are non-additive. Solutions of ethanol and water had been prepared with varying concentrations and a pycnometer was calibrated and used by weighing it along with the liquid samples one at a time, for the accurate measurement of the density of each mixture. The latter was measured in order to calculate for the excess molar volume and partial molar volume for both components. The data were then used for calculating other physical quantities such as molar volume, molar fraction, and molecular weight.
