Transcript text: A 1.05 L solution was made by mixing 462 mL of hexane, which has a density of $0.66 \mathrm{~g} / \mathrm{mL}$, and 0.61 L of toluene, which has a density of $0.87 \mathrm{~g} / \mathrm{mL}$. Calculate the volume percent of hexane in this solution.
Solution
Solution Steps
Step 1: Calculate the Volume of Hexane
The volume of hexane is given as 462 mL. To convert this to liters, we use the conversion factor \(1 \, \text{L} = 1000 \, \text{mL}\):
\[
\text{Volume of hexane in liters} = \frac{462 \, \text{mL}}{1000} = 0.462 \, \text{L}
\]
Step 2: Calculate the Total Volume of the Solution
The total volume of the solution is given as 1.05 L.
Step 3: Calculate the Volume Percent of Hexane
The volume percent of hexane is calculated using the formula:
\[
\text{Volume percent of hexane} = \left( \frac{\text{Volume of hexane}}{\text{Total volume of solution}} \right) \times 100\%
\]
