Question

a sample of 37.7 ml of methyl alcohol is added to enough water to give 675 ml of solution. what is the volume percent concentration of the solution?

Answer 1

The volume percent concentration of the methyl alcohol in water is calculated using the formula (volume of solute / volume of solution) x 100%, which results in approximately 5.59% for a solution of 37.7 mL of methyl alcohol in 675 mL of solution.

Step-by-step explanation:

To calculate the volume percent concentration of the solution, you would use the formula: (volume of solute / volume of solution) x 100%. In this case, the volume of the methyl alcohol (solute) is given as 37.7 mL, and the total volume of the solution after adding it to water is 675 mL.

To find the concentration:

1. Use the provided volumes: 37.7 mL methyl alcohol to 675 mL solution.
2. Apply the formula: (37.7 mL / 675 mL) x 100%.
3. Calculate the concentration: (0.05585) x 100% ≈ 5.59%

Therefore, the volume percent concentration of the methyl alcohol in the solution is approximately 5.59%.
