The most commonly used in expressing of concentration is concentration molarity. The molar concentration is defined as number of moles of solute present in exactly 1L of solutions.
Example of molar concentration
Explanation of example:- First of all we find out the molar mass of H2SO4 so we get 98.1g/mol. Second step of we find out of the moles in present H2SO4, first to find the number of moles for weight of our substance divided by molar mass of our substance therefore moles H2SO4 is 0.0240 mol. Then we find the volume of solution as given in the question 50 ml so it converts into liter 0.050 L. Then our final step is find out the concentration, for concentration Put the value of moles divided by volume of solution the you get answer 0.480 M.
