M stands for Molarity.
Now you may wonder, what is Molarity ?
The answer lies in its unit which is moles/liter. Hence we can define molarity as the number of moles of solute dissolved per litre of the solution. Molarity is a physical quantity and represents the concentration of a solution in moles per liter.
So, Molarity = No of moles of Solute / Volume of Soln in liters
