Answer:

3 × 10¹⁹ kg

Explanation:


\text{Mass of water} = 5.9726 * 10^( 24)\text{ kg Earth } * \frac{5 * 10^(-4)\text{ kg water }}{\text{100 kg Earth}} = \mathbf{3 * 10^(19)}\textbf{ kg water}

The answer can have only one significant figure, because you estimated the percent of water to only one significant figure.
