Answer:
The total mass of water in on Earth's surface is
.
Explanation:
Total planetary surface area = T = ![510,066,000 km^2](https://tex.z-dn.net/?f=510%2C066%2C000%20km%5E2)
Total land area of planet = L = ![148,647,000 km^2](https://tex.z-dn.net/?f=148%2C647%2C000%20km%5E2)
Total water area of planet = W
T = L + W
![510,066,000 km^2=148,647,000 km^2-W](https://tex.z-dn.net/?f=510%2C066%2C000%20km%5E2%3D148%2C647%2C000%20km%5E2-W)
![W=510,066,000 km^2-148,647,000 km^2=361,419,000 km^2](https://tex.z-dn.net/?f=W%3D510%2C066%2C000%20km%5E2-148%2C647%2C000%20km%5E2%3D361%2C419%2C000%20km%5E2)
Volume = Area × Depth
Volume of water on earth = V
V= ![361,419,000 km^2\times 100 km^=36,141,900,000 km^3](https://tex.z-dn.net/?f=361%2C419%2C000%20km%5E2%5Ctimes%20100%20km%5E%3D36%2C141%2C900%2C000%20km%5E3)
![km^3=10^{12} L](https://tex.z-dn.net/?f=km%5E3%3D10%5E%7B12%7D%20L)
![V=36,141,900,000 km^3=36,141,900,000 \times 10^{12} L](https://tex.z-dn.net/?f=V%3D36%2C141%2C900%2C000%20km%5E3%3D36%2C141%2C900%2C000%20%5Ctimes%2010%5E%7B12%7D%20L)
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
![D=\frac{M}{V}](https://tex.z-dn.net/?f=D%3D%5Cfrac%7BM%7D%7BV%7D)
![M=D\times V](https://tex.z-dn.net/?f=M%3DD%5Ctimes%20V)
![M =1 kg/L\times 36,141,900,000 \times 10^{12} L=3.61419\times 10^{22} kg](https://tex.z-dn.net/?f=M%20%3D1%20kg%2FL%5Ctimes%2036%2C141%2C900%2C000%20%5Ctimes%2010%5E%7B12%7D%20L%3D3.61419%5Ctimes%2010%5E%7B22%7D%20kg)
The total mass of water in on Earth's surface is
