A piece of lead weighs 2 kg. What volume does it have?

A piece of lead weighs 2 kg. What volume does it have?



Solution

From the density formula:

p = m / V

Legend
p = density
m = mass
V = volume



We find the volume:

We know from the substance density table that the lead density is = 11.300 kg / m³

We replace the values in the formula and we have:

11.300 kg / m³ = 2 kg / m³ of lead

V lead = 2 kg / 11.300 kg / m³

V lead = 0.000177 m³ or 176.9 cm³

1 m³ = 1,000,000 cm³
