Solution
To calculate the volume percent of hexane in the solution, we need to divide the volume of hexane by the total volume of the solution and then multiply by 100.
Step 1: Identify the volume of hexane and the total volume of the solution. The volume of hexane is 23.0 mL and the total volume of the solution is 89.6 mL.
Step 2: Divide the volume of hexane by the total volume of the solution. 23.0 mL / 89.6 mL = 0.2567
Step 3: Multiply the result by 100 to get the percentage. 0.2567 * 100 = 25.67%
So, the volume percent of hexane in the solution is 25.67%. However, we need to consider the significant digits in our calculation. The volume of hexane (23.0 mL) has three significant digits, and the total volume (89.6 mL) also has three significant digits. Therefore, our final answer should also have three significant digits.
So, the volume percent of hexane in the solution is 25.7%.
