Question

A solid piece of lead has a mass of 36.98 g and a volume of 3.30 cm3. From these data, calculate the density of lead in SI units (kilograms per cubic meter)

Answer 1

We can find the density of lead in SI units from the formula:

$$\rho = \dfrac{m}{V} = \dfrac{36.98g \cdot \dfrac{1kg}{1000g}}{3.30 cm^3 \cdot \dfrac{1m^3}{10^6 cm^3}} = 11206 \dfrac{kg}{m^3}.$$

Answer:

$\rho = 11206 \dfrac{kg}{m^3}.$
