If an impure KHP was in a solution, lets say 25ml and poured into a volumetric flask and filled to the 100ml mark with water. Then titrated against a 0.05M NaOH solution. For example, if it took 35ml to hit end point.
How would I calculate the actual mass of KHP in the initial impure KHP solution. I'm struggling to figure out the moles of KHP in the impure solution. Can you please outline the whole calculation though, thank you.
