Both are equal

Recall the density of water.
The density of water is approximately $1 \text{ kg/L}$ (kilogram per liter) at standard conditions. This means that $1 \text{ liter}$ of water has a mass of $1 \text{ kilogram}$ .
Compare the given quantities.
We are comparing:
- $1 \text{ kg}$ of water (a measure of mass)
- $1 \text{ liter}$ of water (a measure of volume)
Relate mass and volume for water.
Using the density of water, we can determine the mass of $1 \text{ liter}$ of water:
$\text{Mass} = \text{Density} \times \text{Volume}$ $\text{Mass} = 1 \frac{\text{kg}}{\text{L}} \times 1 \text{ L}$ $\text{Mass} = 1 \text{ kg}$
This shows that $1 \text{ liter}$ of water has a mass of $1 \text{ kg}$ .
Conclude the comparison.
Since $1 \text{ kg}$ of water has a mass of $1 \text{ kg}$ , and $1 \text{ liter}$ of water also has a mass of $1 \text{ kg}$ , both quantities are equal.

The correct option is c) Both are equal.
