Calculate the mass of the LIQUID ONLY for EACH of the 5 volumes of liquid.

Results are listed below

Room temperature: 24.1 C

Mass of the graduated cylinder: 20.35 g

Volume 1 = 1.00 mL Mass 1 = 21.16 g

Volume 2 = 2.00 mL Mass 2 = 21.97 g

Volume 3 = 3.00 mL Mass 3 = 22.78 g

Volume 4 = 4.00 mL Mass 4 = 23.59 g

Volume 5 = 5.00 mL Mass 5 = 24.40 g

To find the mass of the liquid, you take the mass of the graduated cylinder + the liquid minus the mass of the empty graduated cylinder.

For volume 1: 21.16 g - 20.35 g = 0.81 g for mass of liquid

For volume 2: 21.97 - 20.35 = 1.62 g

For volume 3: 22.78 - 20.35 = 2.43 g

For volume 4: 23.59 g - 20.35 g = 3.24 g

For volume 5: 24.40 - 20.35 = 4.05 g

someone please answer the questions above

Plot an appropriate graph so that the slope of the graph will determine the average density of the unknown liquid. You must use the masses calculated in question #1 on your What is the density of the unknown liquid in g/mL?

(if you can send the graph to me through a message that would be great)

1.Determine the slope of the graph. Show your slope triangle on the graph and include units.

2.What is the density of the unknown liquid in g/mL?

3.What word describes the mathematical relationship between mass and volume?

4.What is the volume of the liquid when the mass is 2.00 grams? Indicate how you determined your answer.

5.Determine the density of the liquid in kg/m3

6.The unknown liquid is methanol and its density is 791 kg/m3 at 25C. What is your percent error in the experiment
