Question

Glycerol is a syrupy liquid often used in cosmetics and soaps. A 2.50-L sample of pure glycerol has a mass of 3.15×10^3g.

What is the density of glycerol in grams per cubic centimeter?

Answer 1

Answer:

Explanation:

Density = unit mass/ unit volume

1L = 1000cm^3

Unit volume= 2.5 x 1000 = 2500

Unit mass = 3.15×10^3g = 3150

Density = 3150/2500 = 315/250 = 63/50 = 1 13/50 = 1.26g/cm^3
