A) \[0.01\,\,M\,\,N{{a}_{2}}S{{O}_{4}}(aq)\]
B) \[0.01\,\,M\,\,KN{{O}_{3}}(aq)\]
C) \[0.015\,\,M\,\,urea(aq)\]
D) \[0.015\,\,M\,\,glucose(aq)\]
Correct Answer: A
Solution :
Molecules having maximum number of ion, have maximum value of boiling point. In the given options, \[0.01\,\,M\]\[N{{a}_{2}}S{{O}_{4}}\] contains maximum number of ions. So, \[0.01\,\,M\,\,N{{a}_{2}}S{{O}_{4}}\]has highest boiling point.
