2.08 g of a polypeptide was dissolved in 30.00 g of CCl4 and the boiling point elevation for this solution was determined to be 0.980 C. Calculate the molar mass of the polypeptide (Kb for CCl4 = 5.03 Ckg/mol).

Multiple choice:
a. 453 g/mol
b. 1340 g/mol
c. 285 g/mol
d. 356 g/mol

can u please write out the actual formulas i would have to use?
