Question

What is the mass of a 12.31 cubic centimeter piece of copper having a density of 8.96 grams/ cubic centimeter?

Answer 1

• Answer:

m ≈ 110.30 grams

• Explanation:

d = m/V

m = d×V

m = 8.96g/cm³×12.31cm³

m = 110.2976

m ≈ 110.30 grams

Answer 2

Answer:

$\Huge \boxed{\mathrm{110.2976 \ grams}}$

$\rule[225]{225}{2}$

Explanation:

$\sf \displaystyle density = \frac{mass}{volume}$

$\displaystyle \rho = \frac{m}{V}$

Solving for the mass.

$m = \rho \cdot V$

The density of the copper piece is 8.96 g/cm³.

The volume of the copper piece is 12.31 cm³.

$m = 8.96 \cdot 12.31$

$m= 110.2976$

The mass of the copper piece is 110.2976 grams.
