Question

Calculate the molarity of a solution that has 4.5 mol of LiCI dissolved in enough water to make 3.7 L of solution. Record your answer to three decimal places.

Answer 1

Step 1

Molarity is defined as:

molarity (M or mol/L) = moles of solute/volume of the solution (L)

-------------

Step 2

Information provided:

Moles of solute (LiCl) = 4.5 moles

Volume of solution = 3.7 L

-------------

Step 3

Procedure:

Molarity = 4.5 moles/3.7 L = 1.216 mol/L

Answer: Molarity = 1.216 mol/L
