Turn the balance on and press the Tare button to zero the balance. Make sure the display on the balance reads in grams (g). Place a clean dry 25-mL graduated cylinder on the balance and press the Tare button again to zero the balance. Slowly fill the graduated cylinder with water from a water bottle or cup to between 8 and 10 mL; make sure no water is on the outside of the graduated cylinder or on the balance. Record the volume to nearest tenth of a milliliter. Record the mass of the water to the nearest hundredth of a gram. Calculate the density of the water using the formula given in Expt. D. Round your answer to the correct number of significant digits and record it with the correct units. In the Data section, make an appropriate data table (an example data table is shown below) to display all your answers and be sure to include the unit of each number in your table. In the Calculations Section show all your calculations clearly. Mass Volume Density Water

Solution

Since D = m/v

1 milliliter (ml) of water weighs 1 gram (g).

The mass of 10 mL of water is 10 grams.

use a balance to measure the mass in grams.you can find mass by weighing the water. However, since water is a liquid, it needs to be in some sort of container. So in order to weigh the water, they have to weigh the container, too. you will have to subtract the mass of an empty graduated cylinder from the mass of the cylinder and water to get the mass of just the water.

mass of graduated cylinder and water - mass of empty graduated cylinder = mass of water.

so mass of water = 10g

volume = 10ml

so density = 10g/10ml = 1 gm/ml

	mass	volume	density
water	10g	10ml	1gm/ml
