How many liters of a 0.225 M solution of KI are needed to contain 0.935 moles of KI?
alisha [2963]
The result is 4.16 L. Based on the provided information, we calculated the following: Molarity = 0.225 M, Quantity of KI = 0.935 moles, To find Volume: Molarity = moles/Volume, hence Volume = moles/Molarity. Thus, Volume = 0.935/0.225, giving Volume = 4.16 L. Consequently, 4.16 L of KI is required.
