Finding Volume and Mass of Water

Equipment:

Graduated cylinders (small and large)

Tap water

Balance

Paper towels

This lab sheet

Goals:

To determine the mass of a specific volume of tap water.

To determine if there is a relationship between the mass and volume of a liquid.

Hypothesis: (choose one today)

  1. If the volume is increased the mass will go up at the same rate.
  2. If the volume is increased the mass will go up but at a different rate.
  3. If the volume is increased the mass will not be effected

Procedure:

Step 1:

Determine the mass of the small (0 -10 mL) graduated cylinder and record the mass in Data Table 1.

Collect a sample of tap water in the small (0-10mL) graduated cylinder and record the volume in Data Table 1.

Determine the mass of the small (0-10mL) graduated cylinder and tap water sample and record on Data Table 1.

Step 2:

Determine the mass of the large (0-100mL) graduated cylinder and record the mass in Data Table 1.

Collect a sample of tap water in the large (0-100mL) graduated cylinder between the volume of 20 – 50 mL and record the volume in Data Table 1.

Determine the mass of the large (0-100mL) graduated cylinder and tap water sample and record on Data Table 1.

Step 3:

Determine the mass of the large (0-100mL) graduated cylinder and record the mass in Data Table 1.

Collect a sample of tap water in the large (0-100mL) graduated cylinder between the volume of 60ml and 85mL and record the volume in Data Table 1.

Determine the mass of the large (0-100mL) graduated cylinder and tap water sample and record on Data Table 1.

Data Table 1

Mass of Empty Graduated cylinder (grams) / Mass of Graduate Cylinder + Tap Water (grams) / Mass of Tap Water Only (grams) / Volume of Water (mL) / To be used later
Step 1 (0-10mL Sample)
Step 2 (20-50mL Sample)
Step 3 (60-85 mL Sample)

Graphing:

Plot the mass and volume from Data Table 1 on graph paper. Each sample is represented by one point. Use the x axis for the volume and they Y axis for the mass.

Special note about this graph:

This is your 1st graph in this class this year. I know that you have made graphs before.

Show me what you CAN do by completing it to the best of your ability. Don’t show me what you CAN’T do by not trying.
