33. A solution was prepared by mixing 10.0 g of NaCl in 100 g of water. What is the concentration of the solution? 34. If you dissolve 45 g of a solute in 650 mL of solvent, what is the concentration of this solution? 35. If 85 mL of butyl alcohol is placed in a flask, and water is added until the volume is 900 mL, what is the concentration? 36. If 45 ml of solvent is added to 85 mL sample of a 80 % solution, what would the new concentration be? 37. To make a 28 % (m/v) solution, how many ml of solution must be used to the dissolve 46 g of solute? 38. 10.0 mL of a solution of potassium hydroxide was titrated with a 0.10 M solution of hydrochloric acid. 13.5 mL of the acid was required for neutralization. Calculate the concentration of the potassium hydroxide solution. 39. Calculate the concentration of a nitric acid solution (HNO3) if a 20.0 ml sample of the acid required 55.0 ml of a 0.047 M solution of Ba(OH)2 to reach the endpoint of the titration 2 HNO3 + Ba(OH)2 2 H2O + Ba(NO3)2
