Answer:

The answer to your question is

a) 212.7 g

b) 110 g

Explanation:

a) Mass of three moles of Chlorine

Atomic weight of Chlorine = 35.45 g but chlorine is a diatomic molecule then the atomic weight = 2(35.45) g = 70.9 g

               70.9 g of Cl₂ --------------- 1 mol

                  x                  --------------- 3 moles

                 x = 3(70.9)/1

                 x = 212.7 g

b) mass of one mole of K₂S

Molecular mass = (39 x 2) + (32 x 1)

                           = 78 + 32

                           = 110 g

                   110 g of K₂S ----------------  1 mol
