A 22.800 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 75.627 g of water. A 13.386 g aliquot of this solution is then titrated with 0.1052 M HCl. It required 30.21 mL of the HCl solution to reach the methyl red endpoint.
Calculate the weight percent NH3 in the aqueous waste.
