A laboratory hydrogen generator collects the gas produced by bubbling it through water. The total pressure of the gas collected is 751 mmHg. The temperature is 34 °C, at which water vapor pressure is 40.0 mmHg. Calculate the partial pressure of the hydrogen.

Answer:

[tex]711\ \text{mmHg}[/tex]

Explanation:

[tex]P_{total}[/tex] = Total pressure = 751 mmHg

[tex]P_{water}[/tex] = Vapor pressure = 40 mmHg

[tex]P_{gas}[/tex] = Pressure of gas

The total pressure in a system is given by Dalton's law

[tex]P_{total}=P_{gas}+P_{water}\\\Rightarrow P_{gas}=P_{total}-P_{water}\\\Rightarrow P_{gas}=751-40\\\Rightarrow P_{gas}=711\ \text{mmHg}[/tex]

The partial pressure of the hydrogen is [tex]711\ \text{mmHg}[/tex]
