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?
A) 0.091 M
B) 0.67 M
C) 1.3 M
D) 2.6 M

Question

Quizplus · Accepted Answer

Molarity = moles of solute / volume of solution in liters

First, we need to convert the final volume from milliliters to liters:

260.0 mL = 0.260 L

Next, we can use the given number of moles of solute (0.35 mol) and the final volume in liters to calculate the molarity:

Molarity = 0.35 mol / 0.260 L
Molarity = 1.35 M

Therefore, the correct answer is C) 1.3 M.
