(a) Here we are given the mass of oxygen gas as 12 grams

Formula of oxygen gas = O₂

Molar mass  = 2 × 16 = 32 grams.

We know the formula to calculate the no: of moles

No : of moles = Given mass ÷ Molar mass

                      = 12 ÷ 32 

                      = 0.375 moles

(b) Molar mass = given mass / molecular Mass

mm= 22/44

mm= 0.5
