Molarity = moles of solute ÷ liters of solution
M = n / V
Find the mass of the solute in grams
Convert grams of solute to moles using molar mass
Measure the total volume of the solution in liters
Divide moles of solute by liters of solution
Use the formula M = (mass of solute ÷ molar mass) ÷ liters of solution
Keep volume in liters, not milliliters
Keep units as mol/L or M
