Q 22 By the reaction of carbon and oxygen, a mixture of CO and C O
2 is obtained What is the composition by mass of the mixture
obtained when 20 g of O 2 reacts with 12 g of carbon?

Dear Student,

The reactions are C(s)  + 1/2O2(g)  → CO(g)                         n1            n1/2                n1                    C(s)  +  O2(g)  →  CO2(g)                  n2           n2               n2Total mass of C in CO and CO2=(n1+n2) (12 g)Total mass of oxygen in CO and CO2=(n1+2n2)(16 g)Hence, (n1+n2) (12 g)=12 gand (n1+2n2)(16 g)= 20 gor, n1+n2=1 mol and n1+2n2=1
25 molSolving for n1 and n2, we get     n1=0
75 mol and, n2=0 25 molm1=(0
75)(28)=21gmol−1; m2=(0
25)(44)=11 gmol−1m(CO)= 21m(CO2) = 11
