Molar mass of \(H_2SO_4\) \(=\,98\,g\,mol^{-1}\)
Moles in \(95\,g\) \(=\,\frac {95}{98}\,=\,0.969\,mole\)
Volume of \(100\,g\,\,H_2SO_4\)
\(=\,\frac {mass}{density}\) \(=\frac {100\,g}{1.834\,g\,cm^{-3}}\)
\(=\,54.52\,cm^3\) \(=\,54.52\times 10^{-3}\,L\)
Molarity \(=\,\frac {Moles\,of\,solute}{Volume\, of\, Solute \,in\,L}\)
\(=\,\frac {0.969}{54.52\times 10^{-3}}=\,17.8\,M\)
$(M.wt.$ of $CuCl_2 =134.4 $ અને $K_b = 0.52\, , molal^{-1})$
