A 10.0 mL sample of household ammonia solution needed the 38.50 mL of 0.311 M HCl to get the neutralization. Determine
(a) The molar concentration of the ammonia solution and
(b) Convert to % by mass concentration of ammonia (17.0 amu), given a solution density of 0.983 g/mL.
HCl(aq) + NH3H2O(aq) ----->NH4Cl(aq) + H2O
