# 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)?

Liquid Nitrogen is heavier than Gasoline

#### Explanation:

Looking at the expression of density: $D = \frac{m}{V}$ where, $m$ is the mass and $V$ is the volume.

Rearranging this expression to find mass: $m = D \times V$

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.
