The molality of a sulphuric acid solution is 0.2. Calculate the total weight of the solution having 100 gm of solvent.

 

mass of solute = molar mass $\times$ moles of solute $=98\times 0.2=19.6\mathrm{gm}$.
Mass of solvent is $1000 \mathrm{g}$.
Therefore,
mass of solution is $=1000+19.6=1019.6\mathrm{gm}.$.
