Answer:
3.3 mol
Step-by-step explanation:
5.0 mol of NO2
7.0 mol of H2O
The balanced equation is given as;
3NO2 + H2O → 2HNO3 + NO
From the reaction;
3 mol of NO2 requires 1 mol of H2O to produce 2 mol of HNO3
If all the NO2 were used up, there would still be an excess of H2O, so the limiting reactant is NO2.
if 3 mol NO2 produces 2 mol H2O
5 mol NO2 would produce x mol
x = (5 * 2) / 3 = 3.33 mol
To the nearest 0.1 mol, the answer is 3.3 mol
