Question

Transcribed Image Text:**Problem Statement:**
An aqueous solution has a molality of (4.9300x10^-1) m. The density of the solution is (1.42x10^0) g/mL and the solute has a molar mass of (1.660x10^2) g/mol.
**Question:**
What is the mole fraction of solute of this solution?
**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.
This exercise aims to calculate the mole fraction of a solute in an aqueous solution given its molality, density, and molar mass. This type of problem is commonly encountered in chemistry education to deepen understanding of solution concentration measurements.

Transcribed Image Text:**Problem Statement:**
An aqueous solution has a mass percent of solute of \( (3.570 \times 10^1) \% \). The density of the solution is \( (1.3900 \times 10^0) \) g/mL and the solute has a molar mass of \( (1.53 \times 10^2) \) g/mol.
What is the molality of solute of this solution?
**Instructions:**
Enter your answer in scientific notation with 3 sig figs. Do not include any units in your answer.
**Note:** Your answer is assumed to be reduced to the highest power possible.
**Additional Guidelines:**
- Do not round any intermediate calculations.
