🤓 Based on our data, we think this question is relevant for Professor Kizilkaya's class at LSU.

We are asked to **calculate the vapor pressure** for the** second solution at 20 ^{o}C. **

Recall :

$\overline{){{\mathbf{P}}}_{{\mathbf{solution}}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{{\mathbf{X}}}_{{\mathbf{solvent}}}{{{\mathbf{P}}}^{{\mathbf{o}}}}_{{\mathbf{Solvent}}}}$

**We go through the following steps to solve the problem:**

**Step 1. **Calculate the moles water

**Step 2.** Calculate the moles of sucrose (C_{12} H_{22} O_{11} )

**Step 3.** Calculate the mole fraction of water

**Step 4. **Calculate the vapor pressure of the solution

Consider two solutions, one formed by adding 10 g of glucose (C_{6} H_{12} O_{6} ) to 1 L of water and the other formed by adding 10 g of sucrose (C_{12} H_{22} O_{11} ) to 1 L of water.

Calculate the vapor pressure for the second solution at 20 ^{o}C. (The vapor pressure of pure
water at this temperature is 17.5 torr.)
