A complex of cobat with ammonia is analyzed for determining its formula,by titrating it against a strandarized acid as follows : Co(NH_(3))_(x)Cl_(y)(aq)+Hclrarr NH_(4)^(+)(aq)+Co^(y+)+(aq)+Cl^(-)(aq) A 1.8 g complex required 20.00 mL 1.54 M HCl to reach the equivalence point. Also, if the reaction mixture at equivalence point is treated with excess of AgNO_(3) solution, 7.735 g of AgCl precipitate was produced. What is the formula of this complex? ["Given : atomic weight of CO = 59 gmol"^(-1)]
