Calculate the percentage by mass of chlorine in PtCl₂(NH₃)₂. A)23.63 B)11.82 C)25.05 D)12.53 E)18.09

Question

Quizplus · Accepted Answer

The molar mass of PtCl2(NH3)2 is calculated as follows: Pt = 195.08 g/mol, Cl = 35.45 g/mol (x2), N = 14.01 g/mol (x2), H = 1.01 g/mol (x6). Total molar mass = 195.08 + 70.90 + 28.02 + 6.06 = 300.06 g/mol. The mass of chlorine is 70.90 g/mol. The percentage by mass of chlorine is (70.90/300.06) x 100% = 23.63%.
