For the reaction between nitrogen and oxygen to form nitric oxide, beginning with 0.067 mol of N2,

Question

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?

Answer 1

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.

Answer 2

So the answers would be

a. 0.067

b. 0.134

Answer 3

Yes.
