1. Calculate each of the following quantities.
a. grams of solute in 173.4 mL of 0.207 M calcium acetate
b. molarity of 576 mL solution containing 21.1 g of potassium iodide
c. moles of solute in 145.6 L of 0.726 M sodium cyanide

2. Assuming that the volumes are additive, what is the concentration of KBr in a solution prepared by mixing 0.286 L of 0.052 M KBr with 0.590 L of 0.075 M KBr?
