NH4OH + HCl ==> NH4Cl + H2O
mols HCl = M x L = ?
mols NH4OH = same (look at the coefficients in the balanced equation; i.e., 1 mol HCl = 1 mol NH4OH).
M NH4OH = mols NH4OH/L NH4OH = ?
I should note here that it has been shown that NH4OH doesn't exist; i.e, that aqueous NH3 is just that, NH3(aq). In solution it forms NH4^+ and OH^- so the chemistry of aq NH3 is not changed.
