The concentration of ammonia in a commercial cleanser was determined. 25.00 ml of the cleanser was pipetted into a 250 ml Erlenmeyer flask. The 50.00 mL of 0.100 M HCI was added and the reaction was allowed to proceed. NH3 (aq) + HCI (ag) → NHẠCI (s) The excess HCI was then titrated with 0.0500 M Na;CO3 and required 21.50 mL. What was the concentration (M) of NH3 in the original cleanser?

The concentration of ammonia in a commercial cleanser was determined. 25.00 ml of the cleanser was pipetted into a 250 mL Erlenmeyer flask. The 50.00 mL of 0.100 M HCI was added and the reaction was allowed to proceed. NH3 (aq) + HCI (aq) → NH4CI (s) The excess HCI was then titrated with 0.0500 M NazCO3 and required 21.50 mL. What was the concentration (M) of NH3 in the original cleanser?
