Consider the following liquids: 1-pentanol d = 0.8146 g/mL Isopropyl alcohol d= 0.7851 g/mL 2-pentanol d = 0.8098 g/mL Hexane d = 0.660 g/mL You have two unknown samples, each known to be one of the above liquids. a) In determining the density of the first unknown, you weighed a 5.00 mL sample of the liquid, and found the mass to be 3.310 g. What is the identity of the unknown? Explain. b) For the second unknown, a 5.00 mL sample weighed 4.061 g. Based on this data, what can you conclude about the identity of unknown number two? Explain. c)  A perfect cube of jade has a mass of 15.00 g. If jade's density is 3.25 g/ml, determine the edge length of the jade cube.

Question

Consider the following liquids:

1-pentanol d = 0.8146 g/mL

Isopropyl alcohol d= 0.7851 g/mL

2-pentanol d = 0.8098 g/mL

Hexane d = 0.660 g/mL

You have two unknown samples, each known to be one of the above liquids.

a) In determining the density of the first unknown, you weighed a 5.00 mL sample of the liquid, and found the mass to be 3.310 g. What is the identity of the unknown? Explain.

b) For the second unknown, a 5.00 mL sample weighed 4.061 g. Based on this data, what can you conclude about the identity of unknown number two? Explain.

c)  A perfect cube of jade has a mass of 15.00 g. If jade's density is 3.25 g/ml, determine the edge length of the jade cube.
