A 20.285 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. This sample is diluted with 76.385 g of water. A 11.728 g aliquot of this solution is then titrated with 0.1052 M HCl. It required 28.12 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous water.
