No. You do not use M1V1 = M2V2. That formula works very well for titrations that are 1:1; i.e., say NH3 + HCl ==> NH4Cl. It does NOT work for reactions that are not 1:1: i.e., 2HCOOH + Ba(OH)2 ==> Ba(OOCH)2.
By the way I worked this problem for you yesterday. The answer to day is the same. I will try to find it and post it with a link for you.
In a titration experiment, 20.4 mL of 0.883 M π»πΆπππ» neutralize 19.3 mL of π΅π(ππ»)2. What is the concentration of the π΅π(ππ»)2 solution?
Do I use M1V1=M2V2? my answer is 0.467, is this correct?

Here is my work on the problem yesterday.
