Chapter 16, Problem 130E

When $\text{19}\text{.77}\text{g}$ of glucose, ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}\left(180.2\text{g/mol}\right)$, is dissolved in $\text{225}\text{.6}\text{g}$ of an organic solvent, the freezing point of the resulting solution is $\text{1}\text{.06}°\text{C}$ lower than that of the pure solvent. What is the molality of the solution? What is the value of ${\text{K}}_{\text{f}}$ for the solvent?
