Question

Calculate the molar mass of s↓8 ( sulphur )

Answer 1

molar mass of sulphur one atom is 32u
molar mass of sulphur 8 is 32×8=256u

Answer 2

Sulphur is a poly atomic molecule. It is made up of 8 sulphur atoms. Atomic mass sulphur atom = 32 g. Molar mass of sulphur = 8 X 32 = 256 g. b) (i) 32g of oxygen gas = 1 mole         12g of oxygen gas = ?          = 12 X 1 / 32 =  0.375 mole.
