When 3 . 00 g of a substance X ' is dissolved in 100 g of CCl 4 , it raises the boiling point by 0 . 60 K . The molar mass of the substance ' X ' is ___ g mol - 1 . (Nearest integer). [Given K b for CCl 4 is 5 . 0 K kg mol - 1
Correct answer
0
Step-by-step solution
ΔT b = K b ×   molality 0 . 60 = 5 × 3 / M 100 / 100 M = Molar   mass M = 250 .
