Chemistry Notes Molarity

Molarity is one way to measure a solutions concentration; it is the number of moles of solute per liter of solution.

The unit of molarity is mol/L, which can be abbreviated with an uppercase M.

M = moles Liters

Practice Problem #1 What is the molarity of a solution that contains 3.5g of MgCl2 in a 1.13L solution?

Practice Problem #2 A saline solution contains 0.90g of NaCl in exactly 100mL of water. What is the molarity of this solution?

Practice Problem #3 How many moles of solute are present in a 1.5L sample of 0.24M Na2SO4?
