Problem 129P

A 125-g sample contains only glucose $$\mathrm{(C_6H_{12}O_6)}$$ and sucrose $$\mathrm{(C_{12}H_{22}O_{11})}$$. When the sample is added to 0.500 kg of pure water, the resulting solution has a freezing point of $$\mathrm{-1.75~^\circ C}$$. What were the masses of glucose and sucrose in the original sample?

-1.75 ^oC

Step-by-Step Solution:

Step 1 of 4

From the given,

Mass of  sample = 125g

Let the mass of glucose = x

Molar mass of glucose = 180 g/mol

Molar mass of sucrose = 342.34 g/mol
