Here's how to calculate the partial pressure of hydrogen gas:


Calculations

1. Standard Atmospheric Pressure: Standard atmospheric pressure is 760 mm Hg.

2. Partial Pressure of Water Vapor: You're given that the saturated vapor pressure of water at 25°C is 23 mm Hg.

3. Partial Pressure of Hydrogen: According to Dalton's Law:

* Total Pressure = Partial Pressure of Hydrogen + Partial Pressure of Water Vapor
* 760 mm Hg = Partial Pressure of Hydrogen + 23 mm Hg
* Partial Pressure of Hydrogen = 760 mm Hg - 23 mm Hg
* Partial Pressure of Hydrogen = 737 mm Hg

Answer:

The partial pressure of hydrogen gas collected over water under the specified conditions is 737 mm Hg.
