If a solution contains 255ml of ethanol in a 375 ml solution, what is the % of ethanol in that solution?

To calculate the percentage of ethanol in the solution, you need to divide the volume of ethanol by the total volume of the solution and multiply by 100.

Step 1: Determine the volume of ethanol in the solution.
The volume of ethanol is given as 255 ml.

Step 2: Determine the total volume of the solution.
The total volume of the solution is given as 375 ml.

Step 3: Calculate the percentage of ethanol.
Divide the volume of ethanol by the total volume of the solution and multiply by 100.
Percentage of ethanol = (Volume of ethanol / Total volume of solution) * 100

Using the given values:
Percentage of ethanol = (255 ml / 375 ml) * 100

Now, let's calculate this:

Percentage of ethanol = (255 / 375) * 100 = 68%

Therefore, the solution contains 68% ethanol.
