5 litres of alcohol has a mass of 4 kg. Calculate the density of alcohol in (a) `g//cm^(3)` and (b) `kg//m^(3)`.

Explanation

To calculate the density of alcohol given that 5 liters of alcohol has a mass of 4 kg, we will follow these steps:

### Step 1: Convert the volume from liters to cubic meters.
We know that:
1 liter = 0.001 cubic meters.

So, to convert 5 liters to cubic meters:
\[
