A solution is made by dissolving 0.35 mole of LiI in enough water to give a final volume of 260.0 mL. What is the molarity of the solution?
To find the molarity of a solution, you need to know the amount of solute (in moles) and the volume of the solution (in liters).
Given:
- Moles of LiI (solute) = 0.35 mol
- Volume of the solution = 260.0 mL = 260.0 mL x (1 L / 1000 mL) = 0.260 L
Now, we can calculate the molarity using the formula:
Molarity (M) = Moles of Solute / Volume of Solution (in liters)
Plugging in the values, we get:
Molarity (M) = 0.35 mol / 0.260 L ≈ 1.35 M
Therefore, the molarity of the solution is approximately 1.35 M.
