mass of 1 mole of co2 = 12 + 16 +16= 44 gm
hence no of moles in 88 gm co2 = 2 moles
1 mole of co2 contains 2 moles of oxygen
hence there are 4 moles of oxygen atoms in 88 gm of co2
1 mole of CO contains 1 mole of C and 1 mole of O
hence 4 mole of co contains 4 mole of C and 4 moles of O
hence the weight of 4 mole of co = 4(12) + 4(16) = 112 gm
hence no of moles in 88 gm co2 = 2 moles
1 mole of co2 contains 2 moles of oxygen
hence there are 4 moles of oxygen atoms in 88 gm of co2
1 mole of CO contains 1 mole of C and 1 mole of O
hence 4 mole of co contains 4 mole of C and 4 moles of O
hence the weight of 4 mole of co = 4(12) + 4(16) = 112 gm
