The molar mass of the M2O = 2(molar mass of M) + molar mass of oxygen Molar mass of oxygen = 16 Therefore: 231.74 = 2(molar mass of M) + 16 215.74 = 2*molar mass of M molar mass of M = 107.87 grams
Now, from the given formula, we can notice that the metal M is monovalnet and we know that chlorine is monovalent as well. Therefore, the compound formed will be: MCl molar mass of chlorine = 35.5 grams Therefore, molar mass of MCl = 107.87 + 35.5 = 143.37 grams
