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

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

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

Step-by-step explanation:

`\sf \displaystyle density = (mass)/(volume)`

`\displaystyle \rho = (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.

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

Answer 2

• Answer:

m ≈ 110.30 grams

• Step-by-step explanation:

d = m/V

m = d×V

m = 8.96g/cm³×12.31cm³

m = 110.2976

m ≈ 110.30 grams
