The boiling point of benzene is 353.23 K. When 1.80 gm of a nonvolatile solute was dissolved in 90 gm of benzene, the boiling point is raised to 354.11 K. the molar mass of the solute is [Kb for benzene = 2.53 K mol–1]
  • a)
    5.8 g mol–1
  • b)
    0.58 g mol–1
  • c)
    58 g mol–1
  • d)
    0.88 g mol–1
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The boiling point of benzene is 353.23 K. When 1.80 gm of a nonvolatil...
The elevation (ΔTb) in the boiling point = 354.11K-353.23K=0.88K
Substituting these values in expression 

Where, w = weight of solute, w = weight of solute

Hence , molar mass of the slute = 58 gm mol-1
