KOH + HNO3 ==> KNO3 + H2O
so you know it's 1 mol KOH to 1 mol HNO3.
mols HNO3 = M x L = ?
mols KOH = mols HNO3
mols KOH = grams/molar mass. You know mols and molar mass, solve for grams.
HCl + NaOH ==> NaCl + H2O
again 1:1
mols NaOH = M x L = ?
mols HCl = mols NaOH
M HCl = mols/L. You know M and mols, solve for L.
