Verified step by step guidance1
Understand the concept of molarity: Molarity (M) is a measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution.
Identify the given values: You have 5 moles of solute and 2 liters of solution.
Use the formula for molarity: \( M = \frac{\text{moles of solute}}{\text{liters of solution}} \).
Substitute the given values into the formula: \( M = \frac{5 \text{ moles}}{2 \text{ liters}} \).
Perform the division to find the molarity: Divide 5 moles by 2 liters to calculate the molarity of the solution.
