A solution was prepared by dissolving 37.0 g of KCl in 225 g of water. Calculate the mole fraction of the ionic species KCl in the solution. Calculate the molarity of KCl in the solution if the total volume of the solution is 239 mL. Calculate the molality of KCl in the solution.
A solution of a theoretical triprotic acid was prepared by dissolving 5.981 g of solid in...
A solution of a theoretical triprotic acid was prepared by dissolving 5.981 g of solid in enough DI water to make 500.0 mL of solution. 13.87 mL of a 0.446 M solution was required to titrate 20.00 mL of this acid's solution. What is the concentration of the acid solution? What is the molar mass of the acid? Hint: You need to calculate the total moles in the 500.0 mL solution (the full 500.0 mL was NOT titrated).
