Chemistry
since everything is a 1:1 ratio, you know that [acetic acid] = [H3O+] forgot to add that..
Chemistry
first find the [ace acid] (which is 0.0040~M) use Ka constant formula to solve for [H3o+] then use C1V1 = C2V2 where c1= [ace acid] = 0.004~M c2= [initial HCl] = 12M v1= (initial volume of HCl) = 0.01L and you have to solve for v2 i think this is right lol and roman, it's ...
