What does percent by volume equal?

Answer 1

Just figure out what each word means. Lets talk about bleach (Chlorex) for example. Let's put some of it into a gallon container. How much should we put in? I say, ok, lets fill it half ways with the bleach. Lets finish up by filling the rest of the gallon container with water. Now lets talk about what we just did.

We just added 50 percent of bleach to a gallon with water.

That's the answer. We have the percent (50%) and we have the volume (one gallon). So we have talked about percent by volume.

Hope that helps. In real life always add the bleach to the water, its safer.
