Answer 1

Answer:

please follow me

Explanation:

For example, when you buy isopropanol at the store (rubbing alcohol), you'll notice that it says 70% (v/v), which means by volume. This tells you that the solution is 70% isopropanol. So, returning to our rubbing alcohol, 70% (v/v) means that for every 100 mL of solution, there are 70 mL of the solute, isopropanol.
