aaronq · Answer

find how many moles were produced with respect to their coefficients ..
divide one by the other and multiply by 100%

anonymous · Answer

still confused

aaronq · Answer

sorry i misread the problem.. find the number of moles of reactant (NO2)

n=m/MW  ..moles = mass/ molecular weight

then multiply by the coefficient ratio ..

multiply times the molecular weight of HNO3

divide actual/ initial x 100% = 

you should get around 80%

aaronq · Answer

coeffcient ratio is x mol/ 3 NO2 = y mol/ 2 HNO3

and you're finding y

so the ratio is 2/3
