E.16

E.16 The molar mass of the metal oxide M2O is 231.74 g.mol^-1. What is the molar mass of the chloride of this metal?

For this question, what exactly is the chloride within M2O, and how would you go about finding the molar mass of said chloride?

The chloride is MCl, and to find the molar mass you would first find the molar mass of the M in M2O. 231.74 = 2(molar mass of M) + 16. Then by solving this you find that the molar mass of M = 107.87 g/mol. Now you can use this molar mass to find the molar mass of the chloride, MCl. The molar mass of Cl is 35.5 g/mol + 107.87 g/mol = 143.37 g/mol
