Planet Earth has a mass of [tex]5.9726 * 10^{24}\\[/tex] kilograms. And although 70% of the Earth's surface is made of water, the water's mass is only [tex]5 * 10^{-4}[/tex] percent of the Earth's total mass. Use scientific notation to estimate the mass of the planet's water. In your final answer, include all of your estimates and calculations.

Answer:

the estimate of the mass of the planet water be [tex]2.9863 \times 10^{19}[/tex]

Step-by-step explanation:

The computation of the estimate the mass of the planet's water is given below:

As we know that

The mass of the water would be the percentage of the total mass of the earth

So let us assume the W be the mass of the water

So,

[tex]= 5\times10^{-4} (1 \div 100) (5.9726\times10^{24})\\\\= 5 \times (5.9726) x 10^{(-4 + -2 + 24)}\\\\= 29.863 \times 10^{18}\\\\= 2.9863 \times 10^{19}[/tex]

Hence, the estimate of the mass of the planet water be [tex]2.9863 \times 10^{19}[/tex]
