Explanation / Answer

Molality is no of moles of solute presint in one kg of solvent.

here in 1 Kg solvent 35.067 gram( 0.035067 Kg) of salt's ions are present.

So the net solvent will be 1- 0.035067= 0.9649 kg

So For SO42- : Molality = 2.712 / (96* .9649)

= 0.02927

and For Na+ ion: molality =  10.781 / ( 23* 0.9649)

= 0.48579

Other questions:

units for volume = cm3, L, ml

units for pressure= bar, torr, atm, lPa
