An organic chemistry student prepared 1.27 L of a dioxane-toluene solution at 28.0 °C by measuring out 0.86 L of dioxane and 0.44 L of toluene and mixing them.
Calculate the volume percent of dioxane in this solution.
Be sure your answer has the right number of significant digits.
To calculate the volume percent of dioxane in the solution, we first need to calculate the total volume of the solution:
Total volume = Volume of dioxane + Volume of toluene
Total volume = 0.86 L + 0.44 L
Total volume = 1.30 L
Next, we can calculate the volume percent of dioxane:
Volume percent of dioxane = (Volume of dioxane / Total volume) x 100%
Volume percent of dioxane = (0.86 L / 1.30 L) x 100%
Volume percent of dioxane = 0.66153846154 x 100%
Volume percent of dioxane = 66.2%
Therefore, the volume percent of dioxane in the solution is 66.2%.
