Question

Part A. What is the molarity of each of the following?
• 325mL of a solution containing 46.8g of NaHCO3
Part B. What is the final volume, in mL, if 15.0 mL of a 1.80 M KOH solution is diluted to give a 0.300 M KOH solution?

3) For each of the following, first determine if you can solve the question with the given information. If so, solve it on the back. If not, indicate that more information is necessary. A) What is the mass% of a solution containing 4.5 g NaCl and 56 mL H2O? B) What is the volume% of a solution containing 24.3 mL ethanol and 33.6 mL H20? C) What is the volume% of a solution containing 3.5 mL ethanol in a 35.5 mL water/ethanol mixture?
