Colorimetric Analysis Lab

2. Collect data: Click Slice. Choose a piece of Styrofoam and drag it onto the Material Investigation tray. Record the mass and volume, then calculate the density by dividing the mass by the volume. Replace the piece, and then repeat for the remaining pieces.

Procedure: Measure the volume, mass, length and temperature of a variety of items. Create dilution of sugar water.

First I will set up the apparatus as show above. I will add 1.5 grams

Thereafter I used a pipette to meticulously drop in water up to the 250ml mark.

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.

1. Fill the graduated cylinder nearly to the top with water, with a tall glass tube open at both ends (the water level with act as the closed end).

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.

9. The accepted value for the density of water is 1 g/mL and the accepted density for isopropyl alcohol is 0.786 g/mL. Determine the percent error between your calculated densities and the accepted values for both water and isopropyl alcohol. Record the percent error in Data Table 4.

Weight one piece of Zn, got 4.64g. Using 20ml initial volume measuring the volume of Zn, record data 0.7ml. Using equation Density=Mass/Volume, get the density of 100%Zn is 6.63g/ml.

Measure 500ml of tap water in the 500cm3 beaker, then measure 5g of sodium hydrogen carbonate using the 50cm3 beaker and weight scale and place in the beaker of water, using the glass rod to dissolve it into the mixture.

Since this solid block is more dense than water (1.536 g/cm3 > 1 g/cm3) it will sink.

| The density is 0.50 g/mL. There is another choice that has a denser object.

Dispense .5 mL water into the already weighed conical vial, replace cap and face insert on its down side.

After that, it is crucial to convert the mass to volume. The water density at a temperature will aid this process. The compliance of the Volume Occupied by 1.000g of Water Weigh in Air table is deemed necessary throughout the comparison.

Now, the viscosity of each bowl of gelatin must be calculated. This step will require the use of the marble, graduated cylinder and the gelatin.
