Answer 1

2 A. Mola mass of KP = 204-23 g mol"! Moles of KHP = 0.3489 = 0.001704 mot 204.23 mil- Since KHP and NaOH reacts in Ill molar ratio, ( KHP + NaOH — Nakhp + H2O) Moles of Naot reacted a moles of KHP = 0.001704 mol Concentration of NaOH = moles of NaOH volume of solution in L 0.001704 mol 0.01854L 0.0919 M . 3. Apply Miu,= M₂ Vz M, = 12.00, U, = 50.0mL M = 0.750 m, Mui= M2 V₂ Oy V, - MiVo 12.0M X 50 mL 0.750 M =800mL herefore, the solution should be diluted to 800 mL
