Problem: Consider two solutions, one formed by adding 10 g of glucose (C6 H12 O6 ) to 1 L of water and the other formed by adding 10 g of sucrose (C12 H22 O11 ) to 1 L of water.Calculate the vapor pressure for the second solution at 20 oC. (The vapor pressure of pure water at this temperature is 17.5 torr.)

We are asked to calculate the vapor pressure for the second solution at 20 oC. 


Recall :

Psolution = XsolventPoSolvent


We go through the following steps to solve the problem:

Step 1. Calculate the moles water

Step 2. Calculate the moles of sucrose (C12 H22 O11 )

Step 3. Calculate the mole fraction of water

Step 4. Calculate the vapor pressure of  the solution
