What is the molar mass of a solution of 5.00 g of a compound in 25.00 g of carbon tetrachloride (bp 76.8 °c; kb = 5.02 °c/m) that boils at 81.5 °c at 1 atm? (a) outline the steps necessary to answer the question?

214 g/mol

Explanation:

Formula used for Elevation in boiling point :

or,

where,

= change in boiling point  =

= boiling point constant  =

m = molality  =

Thus molar mass of solute is 214 g/mol.
