Question #0f255

Answer 1

106.35 g and 22.302 g respectively.

Explanation:

Atomic weight of chlorine is 35.45 g/mol, but chlorine gas exists as a diatomic molecule, so molar mass is 70.9 g/mol. Therefore 1.50 moles will have a mass of 1.50 x 70.9 = 106.35 g.

Molar mass of silver sulphide `Ag_2S` is 247.80 g/mol, so 0.090 moles would have a mass of 0.090 x 247.80 = 22.302 g
