1.	Question:- Convert into Moles:-a). 12g of oxygen gas.b). 20g of waterc). 22g of carbon dioxide
Answer» into Moles:-a). 12g of oxygen gas.b). 20g of waterc). 22g of carbon dioxideWe know that,the NUMBER moles of a substance,N = Mass (m) (g) / MOLAR Mass (M) a). No. of moles in 12g of oxygen gas = (O2) = 12/32 = 0.375b). No. of moles in 20g of water = (H2O)= 12/18 = 10/9 = 1.11c). No. of moles in 22g of Carbon dioxide = (CO2) = 22/44 = 1/2 = 0.5
