A) 0.015 M urea
B) \[0.01\,M\,KN{{O}_{3}}\]
C) \[0.01\,M\,N{{a}_{2}}S{{O}_{4}}\]
D) \[0.015\,M\,\]Glucose
Correct Answer: C
Solution :
Elevation in boiling point is a colligative property which depends upon the number of solute particles. Greater the number of solute particle in a solution higher the extent of elevation in boiling point. \[N{{a}_{2}}S{{O}_{4}}\to 2N{{a}^{+}}+SO_{4}^{2-}\]
