Hi there, thank you so much for your help.
The information missing is a titration graph with the equivalence point between about 7.8 pH and 25ml of NaOH
A 50.0 mL sample of a solution of a monoprotic acid is titrated with a 0.115 M NaOH solution. The titration curve above was obtained. The concentration of the monoprotic acid is about ________ mol/L.
I did the calculations and I got 0.0611 mol/L, but I am still a little confused about it. Could you help me!!
