A graduated cylinder is placed on an electronic balance, and the scale reads 78.32 g. 10.0mL of glycerine are added, and the scale reads 91.78 g. What is the density of glycerine

1.346 g/mL

Explanation:

The density is defined as the mass of a substance per unit of volume.

In the problem, you add 10.0mL of glycerine. the mass change from 78.32g to 91.78g. The difference is the mass of the glycerine:

Mass glycerine: 91.78g - 78.32g = 13.46g

As the volume added was 10.0mL, the density, δ, in g/mL is:

δ =13.46g / 10.0mL =
