Homework Statement
The total pressure of a mixture of oxygen and hydrogen is 1.00 atm. The mixture is ignited and the water produced is removed. The remaining gas is pure hydrogen and exerts a pressure of 0.34 atm when measured in the same volume and at the same temperature as the original mixture. What was the composition of the original mixture in mole percent?
Homework Equations
2H2 +O2 ---> 2H2O
3. The Attempt at a Solution [/B]
1atm - 0.34atm = 0.66atm H2O
for every 1 mol of H2 that reacts, 2 mols of H2 react so,
0.44atm of the water is H2
0.22 atm of the water is O2
0.34atm +0.44atm = 0.78atm H2O
0.22atm O2
78% of the mixture is H2
22% of the mixture is O2
Can someone check this?
