Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

At an unknown temperature, a solution made of \(5.3400 \times 10^0\) g of a non-volatile solute dissolved in 100.0 g of water has a vapor pressure of \(5.70 \times 10^1\) mm Hg. What is the vapor pressure of pure water (in mm Hg) at this unknown temperature? The molar mass of the solute is \(5.030 \times 10^1\) g/mol.

**Instructions:**

- Enter your answer in scientific notation with 3 significant figures. Do not include any units in your answer.
- Do not round any intermediate calculations.

**Note:** Your answer is assumed to be reduced to the highest power possible.

*(The image contains two hand-drawn loops, one in blue on the left and another in blue on the right, that appear to be random and do not relate directly to the text.)*

**Problem Statement:**

A solution is made of two volatile solutes: Chemical A (with a pure vapor pressure of 80.0 mm Hg) and Chemical B (with a pure vapor pressure of 100.0 mm Hg). The solution has a total vapor pressure of \(9.66 \times 10^1\) mm Hg.

If the solution is known to be made from 3.00 mol of A, how many moles of B must there be in the solution?

**Hints and Instructions:**

- **Total Pressure:** The total pressure is the sum of each chemical's partial pressure: \(P_t = P_A + P_B\).

- **Partial Pressure Formula:** Use \(P_A = X_A \cdot P_A^\circ\) for both the partial pressure of chemicals A and B.

- **Answer Instructions:** Enter your answer in scientific notation with 3 significant figures. Do not include any units in your answer.

- Do not round any intermediate calculations.

**Note:** Your answer is assumed to be reduced to the highest power possible.
