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

Question

Quizplus · Accepted Answer

The molar mass of PtCl2(NH3)2 is 333.2 g/mol. The molar mass of chlorine is 35.5 g/mol. There are two chlorine atoms in the compound, so the mass of chlorine in the compound is 2 * 35.5 = 71 g. The percentage by mass of chlorine in the compound is (71 g / 333.2 g) * 100% = 21.31%.
