The amount of water evaporating from the ocean is significantly larger than the amount of precipitation falling into the ocean. On a global scale, the ocean loses about 577,000 cubic kilometers of water through evaporation each year, whereas it gains just 505,000 cubic kilometers of water from precipitation.
<h3>The Hydrologic Cycle and its Impact on the Ocean</h3>
Is a natural process involving evaporation, precipitation, transport, and recirculation of water through the land and ocean. The key elements in the hydrologic cycle are water and heat.
The hydrological cycle is important for life on Earth, as it regulates air moisture levels and contributes to:
- Food production
- Energy production
- Aquifer recharge
- Flood mitigation
The hydrological cycle also has a significant impact on the ocean, regulating:
- Salinity levels
- Temperature
- Seawater circulation

Effusion rate, R, is inversely proportional to the square root of the molar mass, M:
R α 1 / √M
Let Ra be the effusion rate of a gas with molar mass Ma and Rb the efussion rate of a gas with molar mass Mb, then:
Ra / Rb = √ [Mb / Ma]
You know Ra / Rb = 1.82 and Ma = molar mass of N2 = 28.02 g/mol
=> Mb = [Ra / Rb]^2 * Ma = (1.82)^2 * 28.02 g/mol = 92.81 g/mol
Answer: 92.81 g/mol
