Question

Calculate the mass of a piece of metal if its volume is 2.3 cm’and density is .486 g/cm3.

Answer 1

Answer:

1.12 g.

Explanation:

From the question given above, the following were obtained obtained:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

The density of a material is simply defined as the mass of the material per unit volume of the material. Mathematically, it is expressed as:

Density (D) = mass (m) / volume (V)

D = m/V

With the above formula, we can easily calculate the mass of the metal as shown below:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

D = m/V

0.486 = m/2.3

Cross multiply

m = 0.486 × 2.3

m = 1.12 g

Therefore, the mass of the metal is 1.12 g.
