When 3.00 g of a substance 'X' is dissolved in 100 g of `"CC"l_4`, it raises the boiling point by 0.60 K. The molar mass of the substance 'X' is ________ g `mol^(-1)`. (Nearest integer).
[Given Kb for `"CC"l_4` is 5.0 K kg `mol^(-1)`]

Text Solution

Verified by Experts

The correct Answer is:
250

`DeltaT_b = K_bxx` molality
`0.60=5xx((3//M)/(100//100))`
M = 250
