Question

Which has a greater mass: a kiloliter of liquid nitrogen (density of 0.808 g/mL) or a kiloliter of gasoline (density of 0580 g/mL)?

Answer 1

Liquid Nitrogen is heavier than Gasoline

Explanation:

Looking at the expression of density: `D=m/V` where, `m` is the mass and `V` is the volume.

Rearranging this expression to find mass: `m=DxxV`

Therefore, according to this expression, at constant volume, when `D` increases, the mass will increase too, therefore, for similar volumes the denser liquid will be the heavier.

The answer then, Liquid Nitrogen is heavier than Gasoline.
