Question
Suppose 64.6 mL of dioxane and 57.5 mL of toluene are mixed, and the final solution has a volume of 116. mL. Note that the density of dioxane is 1.03 /gmL.Calculate the volume percent of dioxane in this solution.Be sure your answer has the right number of significant digits.
Solution
To calculate the volume percent of dioxane in the solution, we need to follow these steps:
-
First, we need to find the volume of dioxane in the solution. We know that the volume of dioxane is 64.6 mL.
-
Next, we need to find the total volume of the solution. We know that the total volume of the solution is 116 mL.
-
Now, we can calculate the volume percent of dioxane in the solution. The formula to calculate volume percent is:
Volume percent = (Volume of solute / Total volume of solution) * 100
-
Substituting the values into the formula, we get:
Volume percent = (64.6 mL / 116 mL) * 100 = 55.7%
So, the volume percent of dioxane in the solution is 55.7%. This answer has the right number of significant digits because the volume of dioxane and the total volume of the solution were given to three significant digits.
