Question

What are Normality and Molarity?

Answer 1

Normality:

1. A concentration measure equivalent weight of a gram is equal to the per liter of solutions called normality.
2. The normality is decided by the solution's position in the reaction.
3. In a solution, the corresponding concentration is also known as normality.
4. It is calculated by the formula:

$\mathrm{N}=\frac{\mathrm{Eq}(\mathrm{Number}\mathrm{of}\mathrm{gram}\mathrm{equivalents}\mathrm{of}\mathrm{solute})}{\mathrm{V}(\mathrm{Volume}\mathrm{of}\mathrm{solvent}\mathrm{in}\mathrm{liters})}$

Molarity:

1. In a certain volume of solution, the amount of substance is known as molarity.
2. The moles of a solute per liter of a solution is known as molarity.
3. The molar concentration of a solution is also known as Molarity.
4. It is calculated by the formula:

$\mathrm{M}=\frac{\mathrm{n}(\mathrm{Moles}\mathrm{of}\mathrm{solute})}{\mathrm{V}(\mathrm{Volume}\mathrm{of}\mathrm{liters}\mathrm{of}\mathrm{solution})}$
