Calculate the total mass of water in kg on earth's surface from the following data: total planetary surface area: 510,066,000 km2, land area of planet: 148,647,000 km2 , assume the average depth of water is: 100.0km and the density of water is 1.00g/ml

(using dimensional analysis)

The total mass of water in on Earth's surface is .

Explanation:

Total planetary surface area = T =

Total land area of planet = L =

Total water area of planet = W

T = L + W

Volume = Area × Depth

Volume of water on earth = V

V=

Total mass of total water on the earth = M

Density of the water,D = 1 g/mL = 0.001 kg/0.001 L=1 kg/L

1 g - 0.001 kg

1 mL = 0.001 L

The total mass of water in on Earth's surface is .
