The element M forms the chloride MCl₄ containing 75.0% Cl by mass.What is the molar mass of M?

Question

Quizplus · Accepted Answer

The molar mass of Cl is approximately 35.5 g/mol. Given that Cl constitutes 75% of the mass of MCl, we can set up the equation: 35.5 g/mol / 0.75 = 47.3 g/mol. This calculation gives the molar mass of MCl, not just M. However, the question seems to be asking for the molar mass of the compound MCl (given the context and the values provided), which would be 47.3 g/mol, making E the correct choice. If it were asking for just the element M, we would subtract the mass of Cl from the total mass of MCl.
