i need help with these three questions
Incorrect Question 2 0/1.25 pts 0.678 g of KHP is used to standardize a NaOH solution. If it took 31.55 mL of NaOH to neutralize the KHP, what is the concentration of the NaOH solution? The molar mass of KHP is 204.22 g/mol. KHP + NaOH --> NaKP + H2O Give the answer to 3 sig figs and use units of M 0.0214 Unanswered Question 3 0/1.25 pts A 25.00 mL HCl sample...
