Here each question contains statements given in two columns which have to be matched. Statements in Column I are labelled as A,B,C and D. Whereas statements in column II are labelled as p,q,r and s. The answers to these questions have to be appropriately bublled as illustrated in the following example. If the correct matches are A-p, A-s, B-q, B-r, C-p, C-q and D-p, then the correctly bubbled 4xx4 matrix should look like the following. {:(,"Column I",,"Column II"),((A),"Atomic mass in grams ",p,"Mole"),((B),"Grams molar mass",q,"Grams atoms"),((C),"Avogadro's number",r,"Molecular mass in grams"),((D),"22.4 litres of any gas at NTP ",s,6.022xx10^(23)):}
