stoichiometry & partial pressure
posted by dory .
1 mole of oxygen gas and 2 moles of ammonia are placed in a container and allowed to react at 850 C according to the equation:
4NH3 + 5O2 --> 4NO + 6H2O
Q: if the total pressure in the container is 5.00 atm, what are the partial pressures for the three gases remaining?
I'm confused about how to figure the moles after the reaction occurs. thanks.
