1. Conversions:

A.) How many grams of potassium acetate (MW=98.15 g/mol) are needed to prepare 0.5 L of a 3 M solution?

B.) You have 70 ml of an 60% stock of glucose (180.16g/mol), and you want to prepare 15 ml of a 10% (v/v) glucose solution. How much of your stock and how much water should be used?

C.) You add 20 ml of a 2 M stock solution of NaCl (MW=58.44 g/mol) to 80 ml water. What is the molarity of the final NaCl concentration?
