Dear Student,

3C + 2O2 → 2CO + CO2Given : Moles of C=MassMolar mass=312=0
25 molMoles of O2 =MassMolar mass=532=0
156 molNow, 3 mol of C reacts with 2 mol of O2So, 0
25 mol of C will react with 23×0
25=0 166 mol of O2But we have 0
156 mol of O2 only, therefore, O2 is the limiting reagent here
So, 2 mol of O2 gives 2 mol of COSo, 0
156 mol of O2 will give 22×0
156=0
56 mol of COand,2 mol of O2 gives 1 mol of CO2So, 0
156 mol of O2 will give 12×0
156=0
078 mol of CO2So, Mole fraction of CO=Moles of COMoles of CO+Moles of CO2=0
560 56+0 078=0 560 638=0
88By multiplying it by 4, we get 0
88×4=3 52

3g of carbon react completely with 5g of oxygen leaving no reactants. find mole fraction of carbon monoxide in the product of gases. give your answer multiplying by 4
