How many moles of KBr are present in a 13.2 g sample of KBr?

10-2 moles

Explanation:

recall: volume * concentration = mass (moles in our case)

First, let's simplify our units

200 mL = 0.2 L

0.111 M = 0.111 moles/L

now use the above equation for mass:

0.2 L * (0.111 moles/L) = 0.0222 moles or 2.22 * 10-2 moles
