Question: The titration of a 25.0 mL sample of an aqueous solution containing HNO3 requires 18.6 mL of 0.150 M Ba(OH)2 to reach the equivalence point. The concentration of HNO3 in the original solution was ______ M. What I did: c=n/V n=0.150M * 18.6 mL * (10^-3 L)/1 mL = 0.00279 mol c= 0.00279 mol/25.0 mL * 1 mL/(10^-3 L) = 0.1116 M --> 0.112M It says it's wrong but I think the wording just confused me. I think I have the right idea though but I just don't know where to go with this. How can I fix my math so that I have the correct answer?
