For a practice FRQ, given molarity and volume of a strong base and volume of a weak acid, I used MaVa = MbVb to find molarity of weak acid. The scoring guide provides a point for explicitly finding moles of strong base (M x L) and then using stoic to find the molarity of the weak acid.

I thought MaVa = MbVb is a viable way to find molarity, and the answer was correct too. Would a grader take a point off for what’s functionally the same?
