Answer:
To determine the percent by volume of methanol in the solution, we can use the equation:
Percent by volume = (Volume of methanol / Total volume of solution) * 100
Given that 24.0 mL of methanol is dissolved in 55.0 mL of water:
Percent by volume = (24.0 mL / (24.0 mL + 55.0 mL)) * 100
Percent by volume = (24.0 mL / 79.0 mL) * 100
Percent by volume ≈ 30.38%
The equation used to solve this problem is the percent by volume formula, which calculates the percentage of one component (methanol) in a mixture (solution) based on their respective volumes.
