What is the molar mass of phosphorus pentachloride (PCl₅)? A)177.25 g/mol B)190.30 g/mol C)208.22 g/mol D)172.75 g/mol E)202.82 g/mol

Question

Quizplus · Accepted Answer

To calculate the molar mass of PCl5, we need to add the atomic masses of one phosphorus atom and five chlorine atoms:
Phosphorus: 1 × 30.97 = 30.97 g/mol
Chlorine: 5 × 35.45 = 177.25 g/mol
Total: 30.97 + 177.25 = 208.22 g/mol
Therefore, the molar mass of phosphorus pentachloride (PCl5) is 208.22 g/mol. Option C is the correct answer.
