Calculate the vapor pressure (in torr) at 298 K in a solution prepared by dissolving 32 g of the non-volatile non-electrolye glucose in 186 g of methanol. The vapor pressure of methanol at 298 K is 122.7 torr. Enter your answer to 2 decimal places.

a. 97.06 torr

b. 119.06 torr

c. 149.2 torr

d. 24.8 torr

e. 21.14 torr


We’re being asked to calculate the vapor pressure (in torr) at 298 K in a solution prepared by dissolving 32 g of the non-volatile non-electrolyte glucose in 186 g of methanol (CH3OH). The vapor pressure of methanol at 298 K is 122.7 torr

For this problem, follow the steps:

Step 1. Establish the necessary equations and the van't Hoff factor

Step 2. Find the mole fraction of methanol (solvent)

Step 3. Calculate the vapor pressure
