If a 20.071g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 70.659 g of water. An 11.772 g aliquot of this solution is subsequently titrated with 0.1068 M HCl. It needed 30.77mL of the HCl solution to reach the methyl red endpoint. Compute the weight percent NH3 in the aqueous waste.
