please I need solution as soon as possible thank you 1. You are required to prepare 0.56 M of NaCl for an experiment. Determine the amount of Naci (in gram) required if you only have 350 ml of distilled water. 2. Given that there is 0.04% by volume of CO2 in the air, determine the solubility of CO2 in water at 25 °C and 1 atm (ky for CO2 in water at 25 °C = 29.76 atm/(mol/L)). Formula: n =...
1. A sample of hydrochloric acid (HCI), which is an acid, with a mass of 0.7302 g is dissolved in water and used to standardize a solution of barium hydroxide. An endpoint is reached when 47.81 mL of barium hydroxide has been added. Determine the molarity (in mol/L) of the barium hydroxide solution. Report your answer to four significant figures. Submit Answer Tries 0/13 2. The standardized barium hydroxide solution is then used to titrate 13.86 mL of a solution...
