No of moles = Given mass / Molar mass
Given mass = 48g
Molar mass of
= 32
No of moles = 48/32 = 3/2 = 1.5 g/mol
Given mass = 48g
Molar mass of
No of moles = 48/32 = 3/2 = 1.5 g/mol

So it's oxygen gas and it contains 2 atoms of oxygen each having gram atomic mass 16 g ….so it's gram molecular mass is 32 grams
So we know that …
32 grams of oxygen gas is 1 mole
1 grams of oxygen gas is 1/32 mole
48 grams of oxygen gas is 1/32*48 mole
48 grams of oxygen gas has 1.5 moles
