A chemist dissolves 0.9 g of an unknown monoprotic (one acidic H) acid in water. She finds that 14.6 mL of 0.426 M NaOH are required to neutralize the acid.

a)How many grams of acid are present?

What formula would I use for this question?

One formula you can use is a balanced chemical equation.  Since this is a monoprotic acid, and NaOH, there is a 1 to 1 relationship between acid and base, and it doesn't tell you much, but it does show you that you need to compare moles to moles, but first must convert grams to moles.  Then moels to grams for the answer.

If 0.9 g of acid are dissolved, what mass is that?

Are you sure this is the question?

Yep, that is what I thought. Turns out that`s all they wanted.
