INTRODUCTION TO MOLAR CONCENTRATION OF SOLUTIONS Recall: mole (mol) – the amount of any pure substance (atoms/molecules/ions) containing 6.02x1023 entities. Symbol: n Volume (L) : the space occupied by a solution. Symbol: V MOLAR CONCENTRATION – the amount of solute, in mol, dissolved in one litre of solution. Symbol: C Formula: molar concentration = amount of solute(mol) Volume of solution (L) Or Ex.1- If 1.7 g of sodium hydroxide, NaOH, is dissolved into distilled water to make 350.0 ml of aqueous solution, calculate the molar concentration of the sodium hydroxide solution. Ex.2 – A student needs to make a 0.50 mol/L aqueous solution of iron (III) chloride, FeCl3. What mass, in grams, of FeCl3 will he need to add to distilled water to make 100.0 ml of aqueous solution. Ex.3 – A nurse is administering a 0.75 mol/L intravenous (IV) solution of glucose sugar, C6H12O6, to a patient. If the patient is to receive 23.5 g of glucose, what volume of the solution must she provide for him?
