Question

A small airplane takes on 302 l of fuel. If the density of the fuel is 0.821 g/ml, what mass of fuel has the airplane taken on?

Answer 1

To calculate the mass of the fuel, we use the formula

`m = V *  \rho`

Here, m is the mass of fuel, V is the volume of the fuel and its value is
`V =302 \ L =  302 \ L * (10^(3)m L )/(L) = 302 * 10^(3) \ mL` and
`\rho` is the density and its value of 0.821 g/mL.

Substituting these values in above relation, we get

`m = 302 * 10^(3) \ mL * 0.821 g/mL = 247942 g \\\\ m = 247. 94 \ kg`

Thus, the mass of the fuel 247 .94 kg.
