Abrass bar, density 9.87g/cm3, has a volume of 20.25cm3. what is the mass of this brass bar?

The mass of the bar = 199.87 grams

Explanation:

Given:

Density of a brass bar = 9.87

Volume of bar = 20.25

To find the mass of the brass bar.

Solution:

Density of a body is defined as mass of the body per unit volume of the body.

Thus, we have:

where:

density of the body

mass of the body

Volume of the body

Plugging in the given values.

Solving for

Multiplying both sides by 20.25 .

∴

Thus, the mass of the bar = 199.87 grams
