Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
3. Calculate Molarity Divide the number of moles of NaCl by the volume of the solution to get molarity. 0.21 moles ÷ 0.59 liters = 0.356 M. References Royal Society of Chemistry: Periodic Table ThoughtCo: What Is a Mole in Chemistry?
Consider a problem that asks for the weight of sodium sulfate, Na2SO4, required to prepare 250 milliliters (ml) of a 0.5 M solution. The first step is to calculate the number of moles of Na2SO4required by multiplying the volume of the solution by the molarity: 0.25 liters × 0.5 m...
