Question

A 21.0 kg iron weightlifting plate has a volume of 2670 cm^3. what is the density of the iron plate in g / cm^3

Answer 1

The density of the iron plate is 7.87 g/cm³.

We need to know about density to solve this problem. Density is a parameter that measures how much the mass in a unit volume. It can be written as:

ρ = m / V

where ρ is density, m is mass and V is volume.

From the question above, we know that:

m = 21 kg

V = 2,670 cm³

By substituting the parameter, the density of the iron plate is

ρ = m / V

ρ = 21 kg / 2,670 cm³

ρ = 7.87 x 10‾³ kg/cm³

Convert the density to g/cm³

ρ = 7.87 x 10‾³ kg/cm³

ρ = 7.87 x 10‾³ x10³ g/cm³

ρ = 7.87 g/cm³
