A mixture of H_(2) and water vapor is present in a closed vessel at 20.00^circ C The total pressure of the system is 755.0 mmHg. The partial pressure of the water vapor 17.50 mmHg. What is the partial pressure of H_(2) ? Type in your answer using the correct number of significant figures. square mmHg

To find the partial pressure of in the mixture, we can use Dalton's Law of Partial Pressures, which states that the total pressure of a gas mixture is the sum of the partial pressures of the individual gases in the mixture.Given:- Total pressure, mmHg- Partial pressure of water vapor, mmHgThe partial pressure of can be calculated as: Substituting the given values: Therefore, the partial pressure of is mmHg.
