Concept introduction:

Molarity:

Molarity is defined as the amount of mole of a compound dissolved in an amount of solvent.

$\text{Molarity = }\frac{\text{moles solute}}{\text{litres of solution}}$

$\begin{array}{c}\text{Number of moles = }\frac{\text{m (g)}}{\text{M}}\\ \text{m = Given mass in grams}\\ \text{M = molar mass in grams/mole}\end{array}$
