Sugar Water Density Lab

Density is the amount of matter per unit of measurement (Merriam-Webster. Merriam-Webster, n.d. Web. 26 Aug. 2016.). If water has a density of 1.0 g/mL and you place a substance with a density of 1.8 g/mL the substance will sink because it is denser than water. Density is often measured in g/cm^3 or g/mL because the formula for density is D=m/v.

My hypothesis is that if I add different amounts of sugar to the same amount of boiling water and allow it to be cooled, than the one with the additional cup of sugar will be the one that grows more crystals. I determined that my hypothesis was correct. The glass I chose to add the pure cane sugar did grow much more crystals at a

Density was an important part of this lab. Density can be defined as the ratio of the mass of an object to the volume. To find the density of an object, simply divide mass and volume. The equation looks like this: D=M/V. Density is an intensive property that depends only on the composition of a substance, not the size of the sample.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

First, I will get my materials and set up the scale and 10 mL cylinder and refraction cell. I will check the size of the graduated cylinder to find out the volume. (LxHxW) That will equal 40.5mL for volume. I will see how much the cell weighs alone, and then I will 0 out the scale to see how much the water weighs. Then I will see how much the water and the cell weigh together. I will do this for the cell and cylinder. I will check to see if the density I calculated is what it is supposed to be at 1.00.

Place the beaker on the hot plate, place the thermometer in the beaker and set the hot plate to 5oC.

(Lab: A Penny For Your Thoughts). The density of a matter is equal to the mass divided into the volume. The mass of a matter or object can be found by using a scale. Furthermore, the volume can be found using the method of water displacement. The purpose of finding

In the third stage of this experiment, the density of a liquid was determined and compared to known standards. A 100ml beaker was filled to about half-full with room-temperature distilled water. The temperature of the water in ◦C was recorded in order to compare to known standards later. A 50ml beaker was then weighed on a scale in order to determine mass and recorded. A sample of the distilled water with an exact volume of 10ml was then placed in the 50ml beaker using a volumetric pipette. The 50ml beaker with the 10ml of water was then weighed again and the initial mass of the beaker was subtracted from this mass to obtain the mass of the 10ml of water. With the volume and the mass of the water now known, density was calculated using d = m/V and recorded in g/ml. This process was then repeated to check for precision and compared to standard values to check for accuracy. Standard values were obtained from CRC Handbook, 88th Ed.

1.) Measure out 20ml out of the water and place it into a glass beaker

Pour approximately 50 mL of room-temperature distilled water into the glass beaker by using the estimated volume on the beaker.

Concentration of solutionsconcentrations were kept constant by using the same digital scale (with an uncertainty of 0.01 g) to measure the amount of glucose to be added to the water

Create a water bath by filling ½ of the 100 mL beaker with cool water, adding crushed ice to the beaker so the water level is just below the top, and sprinkling salt into the beaker

This table compares the density and the percent of sugar. Based on this table flat soda would

Measure the correct amounts of sugar and water into each of the labeled cups. One at a time, place a cup on the scale and add the sugar directly, but before you do so, hit the button “on” or “zero” to restart the scale. This way, the scale will only measure the amount of sugar that is poured into the cup and not the cup itself. The chart shown below will tell you how much sugar to weigh in each cup. Once you have finished, add 50 mL of water to each cup using the graduated cylinder. Then stir your cups with the spoon until the sugar has dissolved in each solution.

Rinse the thermometer with tap water and dry. Insert the thermometer in the calorimeters top and measure the initial temperature of the base 28.2∘C
