Calculate the molarity and the molality of concentrated of hydrochloric acid The specific gravity of this solution is 1.29 and its weight percent is solution is 37.5%(2 points) 10. In Part 1 of a reaction, A 3.1586 g sample of KHP (HKCaH404) required 28.5446 mL of NaOH solution to reach a phenolphthalein endpoint. Calculate the molarity of the NaOH. (2 points) 11. In Part 2 of a reaction, A 20.00 mL sample of HCl was titrated with the NaOH solution from Part 1. To reach the endpoint required 23.72 mL of the NaOH. using the information from question #24, calculate the molarity of the HCL (2 points)
