4.22 M means 4.22 moles of H2SO4 are present in 1 L of the solution.
Given that the density of the solution is 1.2g/mL
On multiplying the density with the 1L volume of the solution, one can find out the nmass of 1 L of the solution.
On getting the mass of the solution, subtract the mass of the H2SO4 from the mass of the solution to get the mass of the solvent.
Hence, then proceed for the calculation of molality.
