For the reaction between nitrogen and oxygen to form nitric oxide, beginning with 0.067 mol of N2,
N2(g) + O2(g)= 2 NO(g)
a. how many moles of O2 are required to completely consume the N2?
b. how many moles of NO are obtained when the N2 is completely reacted?
You can convert from anything to anything by using the coefficient in the balanced equation.
a. 0.067 mol N2 x (1 mol O2/1 mol N2) = ?
b. 0.067 mol N2 x (2 mol NO/1 mol N2) = ?
Note that the unit you don't want to keep cancels but the unit to which you wish to convert stays.
So the answers would be
