Question: What is the volume percent concentration of a solution containing 30 mL of ethanol in 150 mL of solution?

Options:

Correct Answer: 25%

Solution:

Volume percent = (volume of solute / total volume) x 100 = (30 mL / 150 mL) x 100 = 20%.

What is the volume percent concentration of a solution containing 30 mL of ethanol in 150 mL of solution?

What is the volume percent concentration of a solution containing 30 mL of ethanol in 150 mL of solution?

Step 1: Identify the volume of the solute (ethanol) in the solution. In this case, it is 30 mL.
Step 2: Identify the total volume of the solution. Here, it is 150 mL.
Step 3: Use the formula for volume percent concentration: Volume percent = (volume of solute / total volume) x 100.
Step 4: Plug in the values: Volume percent = (30 mL / 150 mL) x 100.
Step 5: Calculate the fraction: 30 mL divided by 150 mL equals 0.2.
Step 6: Multiply the result by 100 to convert it to a percentage: 0.2 x 100 equals 20%.
Step 7: Conclude that the volume percent concentration of the solution is 20%.
