    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%

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