A 24.156 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 71.374 g of water. A 11.856 g aliquot of this solution is then titrated with 0.1073 M HCl . It required 29.24 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
