# 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.)

###### FREE Expert Solution

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

Recall :

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
