Question

Problem 2: An alcohol based sanitizer Contains 200 ml Isopropyl Alcohol in a 500 ml solution. Calculate the percentage (use 1 formula)​

Answer 1

So, the alcohol-based sanitizer contains 40% Isopropyl Alcohol.

Explanation:

To calculate the percentage of Isopropyl Alcohol in the 500 ml solution, you can use the following formula:

Percentage= Part/ Whole ×100

In this case:

The "Part" is the amount of Isopropyl Alcohol, which is 200 ml.

The "Whole" is the total solution volume, which is 500 ml.

Now, plug these values into the formula:

Percentage= 200 ml/500 ml ×100

Percentage= 2/5 × 100

Now, calculate the percentage:

Percentage=0.4×100=40%

So, the alcohol-based sanitizer contains 40% Isopropyl Alcohol.
