Answer:

524.82 g Cl2

Explanation:

Balanced Equation:

2Al(s) + 3Cl(g) ⇒ 2AlCl (s)

Al: 26.982 g/mol     Cl: 35.453 g/mol

266.28g Al x 1mol Al/ 26.982g Al x 3mol Cl2/ 2mol Al x

35.453g Cl2/ 1mol Cl2 = 524.82 g Cl2

Two compounds contain only tin and chlorine. the ratio of the masses of chlorine combined with 1.00g of tin in the two compounds
Nesterboy [21]
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
