A nurse wants to add water to 30 ounces of a 10% solution of benzalkonium chloride to dilute it to an 8% solution. How much water must she add?
7.5 oz
Using the standard dilution equation:
We already have 30 oz, so just need to add 7.5 oz.
I have a free ebook that covers moles and molarity, percentage solutions, and dilutions, which you may find useful.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
