A mixture of gases with a total of pressure of 100 ATM is 75% N₂ and 25% O₂ what is the gas pressure of N₂ gas in this mixture.

Answer:

Dalton's Law of Partial Pressures states that the total pressure in a gas mixture is the sum of the partial pressures of each individual gas.

$$P_{\text{total}} = P_{\text{gas a}} + P_{\text{gas b}} + P_{\text{gas c}} + \text{etc}$$

Therefore,

$$P(N_2) = 100 \cdot 0.75 = 74 \text{ ATM}$$
