Question

Calculate the molarity of an acetic acid solution if 55.63 mL of the solution is needed to neutralize 104 mL of 1.74 M sodium hydroxide. The equation for the reaction is 

HC ₂H ₃O ₂( aq)    +     NaOH( aq)     ---->     Na ⁺( aq)     +     C ₂H ₃O ₂ ^-( aq)    +    H ₂O( aq)

Answer 1

The stoichiometry is 1:1, so you can use the titration equation M_AV_A = M_BV_B You are given 3 out of 4 variables. Solve for the one that you don't know, M_A. It's ok to use ml because they are on both sides of this equation.
