![**Title:** Determining Mole Fractions in a Methanol-Ethanol Solution
**Description:** This exercise involves calculating the mole fractions of methanol \((\text{CH}_4\text{O})\) and ethanol \((\text{C}_2\text{H}_6\text{O})\) in a solution. Both components are mixed in equal masses. Your task is to determine the mole fraction of each component to at least three significant figures.
**Instructions:**
1. Given that equal masses of methanol and ethanol are mixed, calculate the number of moles for each component.
2. Use the molecular weights of methanol and ethanol to find the total number of moles.
3. Determine the mole fraction for each component.
**Formulae:**
- Mole fraction formula:
\[
X_{\text{component}} = \frac{\text{moles of component}}{\text{total moles in solution}}
\]
**Calculation Fields:**
- \( X_{\text{meth}} = \) [Input your calculation here]
- \( X_{\text{eth}} = \) [Input your calculation here]
**Objective:**
Understand and apply the concept of mole fraction in solutions, enhancing your grasp on solution chemistry and stoichiometry.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fffdcabf9-292f-4966-b855-5c60442e2ad4%2Fb7a249d3-c204-413d-904f-ce01833d55ae%2Fskqdof.jpeg&w=3840&q=75)
