Explanation:

Molar mass of 1 mole of CO2 = Molar mass of C+2 x Molar mass of O = 12 + 32 = 44.

⟹ 44 gm of CO2

= 1 mole of CO2

So, 22 gm of CO2= 44/22

moles of CO2= 0.5 moles of CO2

Answer 2

Molar mass of 1 mole of CO2 = Molar mass of C+2 x Molar mass of O = 12 + 32 = 44.

⟹ 44 gm of CO2

= 1 mole of CO2

So, 22 gm of CO2= 44/22

moles of CO2= 0.5 moles of CO2
