Two compounds contain only tin and chlorine. the ratio of the masses of chlorine combined with 1.00g of tin in the two compounds is 2. if one compound has the formula sncl2, what is the formula for the other compound?

Compound A : SnCl2

the mass ratio of Cl and Sn: 71 g Cl / 119 g Sn = 0.579 g Cl / 1 g Sn

Compound B: the ratio of mass of chlorine per 1 g Sn is twice the ratio of chlorine per 1 g Sn in compound A = > 1,194 g Cl / 1 g Sn = 142,086 g Cl / 119 g Sn

=> the number of chlorine / 1 atom Sn = 142.086 / 35.5 = 4.

=> the formula of B: SnCl4
