SOLVED: A student was asked to determine the concentration of ammonia, a volatile substance, in a commercially available cloudy ammonia solution used for cleaning. First, the student pipetted 20.85 mL of the cloudy ammonia solution into a 409.81 mL conical flask. Then, 92.01 mL of 0.145 mol/L HCl(aq) was immediately added to the conical flask, which reacted with the ammonia in solution. The excess (unreacted) HCl was then titrated with 0.039 mol/L Na2CO3(aq). It was found that 20.3 mL of Na2CO3(
