Normality Calculator
Normality abbreviated N, specifies the number of gram equivalents of solute per liter of solution. Concentrations of solutions in volumetric calculations are often expressed in terms of normality.

"Normality (N) is defined as the number of equivalents of solute per liter of solution."

Normality Calculator calculates the equivalents of solute per liter of solution.

Steps for Normality Calculator

Step 1 :  

Read the problem carefully and identify the values given in the problem.

Step 2 :  

Apply the normality formula and substitute the values in order to get the normality value.

Normality = $\frac{Equivalent\ of\ solute}{Liters\ of\ solution}$

  1. What is the normality of a solution of sulfuric acid when 0.248mol dissolved in 250.0mL of solution?

    Step 1 :  

    Equivalent of solute = 0.248 mol $\times$ 2 equivalents mol

    Liters of solution = 250mL = 0.250L

    Step 2 :  

    Normality = $\frac{0.248\ mol \times 2\ equivalents\ mol}{0.250L}$

    Normality = 1.98N

    Answer  :  

    Normality of the solution is 1.98N

  2. Calculate the normality of a sodium hydroxide solution containing 2.50g of NaOH in 200mL of solution.

    Step 1 :  

    Equivalent weight of NaOH = Formula mass/1
    Equivalent weight of NaOH = 40/1 = 40

    40g NaOH = 1 g-equivalent
    2.50g NaOH = $\frac{1}{40g} \times 2.50g$

    = $\frac{1}{16}$ g-equivalent

    Step 2 :  

    1000 mL solution contains

    $\frac{1}{16}$ g-equivalent $\frac{1000mL}{200mL}$ = $\frac{5}{16}$ g-equivalent

    Therefore Normality of solution = $\frac{5}{16}$N

    Normality of solution = 0.3125N

    Answer  :  

    The normality of given sodium hydroxide solution is 0.3125N
