We have to convert the following into moles.
32 g of oxygen gas = 1 mole
Given that 12 g of oxygen gas
No: of moles = given mass / molar mass
= 12 / 32 = 0.375 mole
18 g of water = 1 mole
Given that 20 g of water
No: of moles = given mass / molar mass
= 20 / 18 = 1.111 mole
44 g of carbon dioxide = 1 mole
Given that 22 g of carbon dioxide
No: of moles = given mass / molar mass
= 22 / 44 = 0.5 mole
