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)`]

3g of X dissolve in 100g of "CC"l_4 which increases the bioling point by 0.6. Find molar mass of X .Given K_b of "CC"l_4 = 5KKg/mol
