battery acid is 4.22M aqueous H2SO4 solutionn aNd has density of 1.21 g/cm3.what is the molality of H2SO4??????//

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.
