Weight of 1 litre milk is `1.032 kg`. It contains butter fat (density `865 kg m^(-3))` to the extent of `4.0%` by wt`//`volume. Calculate the density of the fat -free skimmed milk.

Explanation

To calculate the density of fat-free skimmed milk, we will follow these steps:

### Step 1: Determine the weight of 1 cubic meter of milk.
Given that the weight of 1 liter of milk is 1.032 kg, we can find the weight of 1 cubic meter (1000 liters) of milk.

\[ \text{Weight of 1 m}^3 \text{ milk} = 1.032 \, \text{kg/liter} \times 1000 \, \text{liters} = 1032 \, \text{kg} \]
