We’re being asked to determine the amount of KBr needed to prepare 0.80 L of 1.6x10-2 M KBr.
Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters).
In other words:
Describe how you would prepare each of the following aqueous solutions, starting with solid KBr.
0.80 L of 1.6×10−2 M KBr
