Question

What is the mass of gasoline (p= 0.680 g/cm^3) in a 94.6 L gasoline tank?

Answer 1

Given Density = 0.680 g/cm3

Volume =96.3 L

Changing units

Density = 0.68 *10³ Kg/m3 = 680 kg/m3

Volume = 96.3 L= 96.3*10^-3 m³ = 0.963 m³

Density = Mass /Volume

Mass= Density * Volume = 680*0.963 = 654.84 kg
