Question

An aqueous solution containing 1g of urea boils at `100.25^(@)C`. The aqueous solution containing 3g of glucose in the same volume will boil be
A. `100.75^(@)C`
B. `100.5^(@) C`
C. `100^(@)`C
D. `100.25^(@)C`

Answer 1

Correct Answer - D
`n_(1)` of 1 g urea `=1/60 "mol",`
`n_(2)` of 3g glucose `=3/180 = 1/60` mol
Hence, it will boil at the same temperature as `n_(1) = n_(2)`
