Please tell me if these are right!

Question

1.How many milliliters of 0.215 M NaOH solution are needed to completely neutralize 2.50 ml of 0.825 M H2SO4 solution?
I got 19.2 ml

2. A 10.0-ml sample of vinegar which is an aqueous solution of acetic acid HC2G3O2 requires 16.5 ml of 0.500M NaOH to reach the endpoint in a titration what is the morality of the acetic acid solution?

I got 0.00825 M acetic acid solution

thank you

Answer 1

1. correct
2. acetic acid reads CH3COOH when I was in school
10.0*M = 16.5*0.500
I get M=0.825
