Question

The freezing point depression constant, K_f, for camphor is very large, 37.7 ⁰C•kg/mol, making camphor a useful solvent to determine the mass of larger molecules, such as peptides. 122.5 mg of a peptide dissolved in 1.50 g of camphor gives a freezing point depression (ΔT_f) of 1.13 ⁰C. What is the molecular mass of the protein?
