Question- A 22.111 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 70.804 g of water. A 11.655 g aliquot of this solution is then titrated with 0.1079 M HCl. It required 30.25 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
Depict your all calculation in detail so I can understand the solution thoroughly
