Gasoline has a density of 0.69g/cm cubed. Calculate the mass of a litre of gasoline.

From the information given, the gasoline has a density of 0.69g/cm³ and the volume is 1 liter.

We first need to realize density of liquids is expressed in g/ml rather than g/cm³ which is for solids.

So we shall assume density of gasoline here is 0.69g/ml

We then convert liters to ml so 1 liter = 1000ml

mass = density * volume

mass = 0.69g/ml * 1000ml

mass = 0.69 * 1000

mass = 690

Therefore the mass the gasoline is 690 grams.
