Chapter 13, Problem 129E

A 125-g sample contains only glucose $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}\right)$ and sucrose $\left({\text{C}}_{\text{12}}{\text{H}}_{\text{22}}{\text{O}}_{\text{11}}\right)$. When the sample is added to 0.500 kg of pure water, the resulting solution has a freezing point of -1.75°C. What were the masses of glucose and sucrose in the original sample?
