An aqueous solution containing 1 g of urea boils at 100.25 °C. The aqueous solution containing 3 g of glucose in the same volume will boil at

Options

A. `100.75^@C`
B. `100.5^@C`
C. `100^@C`
D. `100.25^@C`

Answer

D

Explanation

Number of moles of urea `= 1/60`
Number of moles of glucose `= 3/180 = 1/60`
Since, the molar concentration of the two solutions is same (amount of solvent given is same), the two solutions boil at the same temperature,
