A 10.231-g sample of window cleaner containing ammonia was diluted with 39.466 mL of 0.1063 M HCl to reach the bromocresol green end point. Find the weight percent of NH3 (FM 17.031) in the cleaner.

Answer 1

mols HCl = M x L = ?
moles HCl = moles NH3
g NH3 = moles x molar mass.
%NH3 = (mass NH3/mass sample)*100 = ?
