Question

Stoichiometry question: KOH+HNO3---> KNO3+H2O

Answer 1

Figured out that KOH was 2.597 mol, and HNO3 was 7.184 mol.

Answer 2

But since the ratios are 1:1:1:1, what happens here?

Answer 3

Then the substance with the least number of moles is the limiting reagent. Thus your reaction can only produce according to that number of mole's ratio.
