Dalton's Law of Partial Pressures states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of each individual gas in the mixture. The formula representing Dalton's law of partial pressure can be expressed as:
\[ P_{\text{total}} = P_1 + P_2 + P_3 + \ldots + P_n \]
Where:
- \(P_{\text{total}}\) is the total pressure of the gas mixture.
- \(P_1, P_2, P_3, \ldots, P_n\) are the partial pressures of each individual gas in the mixture.
This equation indicates that if you know the partial pressures of the individual gases, you can calculate the total pressure of the gas mixture by summing those values.
