An unknown chlorohydrocarbon has 3.55 % of chlorine. If each molecule of the hydrocarbon has one chlorine atom only; chlorine atoms present in 1 g of chlorohydrocarbon are :(Atomic wt. of Cl = 35 .5 u ; Avogadro constant = 6 .023 × 10 23 mol – 1 )

TestHub · Accepted Answer

C x H y Cl % Cl = 3 .55 Weight of C l = 1 × 3.55 100 n C l - = 1 × 3.55 100 × 35.5 No . of Cl - ion = 1 × 3 .55 100 × 35 .5 × 6 .023 × 10 23 = 6 .023 × 10 20
