Calculate the density of 60.7 g of an isopropyl alcohol-water mixture (commercial rubbing alcohol) that has a volume of 64.1 mL. Be sure your answer has the correct number of significant figures.

Answer 1

Density = mass / volume

Density = 60.7 g / 64.1 mL
Density = 0.946 g/mL

Therefore, the density of the isopropyl alcohol-water mixture is 0.946 g/mL. This answer has three significant figures.
