6g of metal M react completely with 23.66g of chlorine to form 29.66g of the metallic chloride. Find the empirical formula of the metallic chloride. (M = 27, Cl = 35.5)
Convert grams to mols.
6/27 = ?
23.66/35.5 = ?
Now find the ratio of M to Cl. The easy way to do that (if the answer isn't obvious at this point) is to divide the smaller number by itself, then divide the other number by the same small number.
6g/M27 23.66/35.5 = 0.6 0.2/0.2=1 0.6/0.2 = 3 EMPIRICAL FORMULAR = M1CL3 CHILEZ
