Question

3. Calculate the molar concentration of an NaOH solution that required 15.81 ml to com pletely neutralize 0.509 g of KHP (Remember that the "P" in KHP does not mean phos- phorus. See the molecular structure and molar mass of KHP given earlier in the lab.) KHP(s) + NaOH(aq) - NaKP(aq) + H,O(C) 4. Calculate the mass of KHP that will react completely with 25.00 mL of 0.1750 M NaOH. 5. Write the balanced equation for the reaction that occurs when aqueous HCl is added to solid Caco, and the solution is heated. 6. Calculate the mass of solid NaOH needed to prepare 250.0 mL of 0.1000 M NaOH solu- tion
