If you have a .045 M solution of sodium hydroxide, how many mL of the solution do you need to neutralize 6.5 mL of a .055 M sulfuric acid solution?

do i use the equation M1V1 = M2V2??

or is that for dilutions

It's for dilutions AND this type problem when the reaction between the acid and base is 1:1 as it is in this case.
