A 2 cm cube made of acrylic has a mass of 19.7 g . What is the density of the acrylic?

9.85g/cm3

Explanation:

The following data were obtained from the question:

Mass = 19.7g

Volume = 2cm3

Density =..?

Density of a substance is simply defined as the mass per unit volume. It is represented mathematically by:

Density = Mass /volume

With the above formula we can find the density of the acrylic as follow:

Density = 19.7g/2cm3

Density = 9.85g/cm3

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
