Match the following columns: Column I Column II (i) Percentage of iron in K 3 Fe ( CN ) 6 (a) 32 (ii) Relative molecular mass of CH 3 OH (b) 6 . 023 × 10 23 molecules of chlorine (iii) One mole of chlorine contains (c) 17 . 02 %

(i) Percentage of iron in K 3 Fe ( CN ) 6 is 17 . 02 % Percentage composition of an element = mass of the element in the compound total mass of the compound × 100 = 56 329 = 17 . 02 % (ii) Relative molecular mass of CH 3 OH is 32 . Relative molecular mass is the ratio of the average mass of one molecule of an element or compound to 1 12 th of the mass of an atom of carbon - 12 . (iii) One mole of chlorine contains is 6 . 023 × 10 23 molecules of chlorine. It is called the Avogadro's number.
