Step 1 :  

Read the problem and list out the given quantities.



Step 2 :  

The Molar Concentration is given by the formula:
Ci = $\frac{n_{i}}{V}$


Where Ci = Molar Concentration,
ni = no of moles present,
V = Volume of the solution.


Substituting any of the two given quanties among the three, we get the desired quantity.

  1. What is the Molar concentration of a solution containing 50g of Sodium chloride in 2 litres of water?


    Step 1 :  

    One mole of sodium Chloride is 58.5 grams.
    So 50 gms of Sodium chloride = $\frac{50}{58.5}$


    No of moles present ni = 0.85 moles,


    Volume of solution V = 2 litres.


     



    Step 2 :  

    The Molar Concentration is given by the formula:
    Ci = $\frac{n_{i}}{V}$


        = $\frac{0.85}{2}$
        = 0.425 moles per litre.



    Answer  :  

    The Molar Concentration is 0.425 moles per litre.



  2. Calculate the Molar concentration of KOH in 5 litres of solution?


    Step 1 :  

    given: No of moles of KOH = 2.75 moles


    Volume of solution = 5 litres.



    Step 2 :  

    Molar Concentration of KOH = $\frac{No\ of\ moles\ of\ KOH}{Volume\ of\ solution\ in\ litres}$
                                                 = $\frac{2.75\ moles}{5 L}$

                                                 = 0.55 M.



    Answer  :  

    The Molar Concentration of KOH in 5 litres solution is 0.55 M.
