Planet earth has a mass of 5.9726 × 10 24 kilograms. and although 70% of the earth's surface is made of water, the water's mass is only 5 × 10 -4 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.

mass of water = 2.9863 * 10^19 kg

Step-by-step explanation:

Mass of Earth: 5.9726 * 10^24 kg

Mass of water is 5 * 10^(-4) % of the mass of Earth

To find a percent of an amount, multiply the percent by the amount.

To change a percent to a decimal, divide the percent by 100.

The mass of the water on Earth is the percent multiplied by the mass of Earth.

mass of water = 5 * 10^(-4) % * 5.9726 * 10^24 kg

We now change the percent to a decimal by dividing the percent by 100.

mass of water = 5 * 10^(-6) * 5.9726 * 10^24 kg

mass of water = 5 * 5.9726 * 10^(-6) * 10^24 kg

mass of water = 29.863 * 10^(-6 + 24) kg

mass of water = 29.863 * 10^18 kg

The number above is not in scientific notation because 29.863 is not from 1 to under 10. We divided 29.863 by 10, and multiply 10^18 by 10.

mass of water = 2.9863 * 10^19 kg
