What is the total pressure (mmHg) of a gaseous mixture of 3.7 g of hydrogen gas and 9.1 g of oxygen gas in a 3.24-L flask if the partial pressure of hydrogen is 318 mmHg?
1 Answer
Approx.
Explanation:
Given constant temperature, and volume, which we certainly have here (even though we don't know their magnitudes), pressure is proportional to the number of moles of gas, or vice versa.
We are given that
And given the proportionality between moles and pressure,
And finally,
Note that I converted the
