**Problem Statement:**An automobile antifreeze solution contains 2.70 kg of ethylene glycol, $ \text{CH}_2\text{OHCH}_2\text{OH} $, and 1.90 kg of water. Find the mole fraction of ethylene glycol in this solution. What is the mole fraction of water?**Objective:**Calculate the following:- Mole fraction of ethylene glycol- Mole fraction of water**Solution Steps:**1. **Calculate the number of moles of each component:** - **Ethylene glycol ($ \text{CH}_2\text{OHCH}_2\text{OH} $):** - Molar mass = 62.07 g/mol - Mass = 2.70 kg = 2700 g \[ \text{Moles of ethylene glycol} = \frac{2700 \text{ g}}{62.07 \text{ g/mol}} \] - **Water ($ \text{H}_2\text{O} $):** - Molar mass = 18.02 g/mol - Mass = 1.90 kg = 1900 g \[ \text{Moles of water} = \frac{1900 \text{ g}}{18.02 \text{ g/mol}} \]2. **Calculate the mole fractions:** - **Total moles = Moles of ethylene glycol + Moles of water** - **Mole fraction of ethylene glycol:** \[ \text{Mole fraction of ethylene glycol} = \frac{\text{Moles of ethylene glycol}}{\text{Total moles}} \] - **Mole fraction of water:** \[ \text{Mole fraction of water} = \frac{\text{Moles of water}}{\text{Total moles}} \]**Outputs:**- Mole fraction of ethylene glycol - Mole fraction of water Use the above methods to calculate the specific mole fractions for ethylene glycol and water based on the provided masses.
