A Protein has been isolated as sodium salt with their
molecular form\(\mathrm{Na}_{2} \mathrm{P}\)(this notation means\(\mathrm{xNa}^{+}\)ions
are associated with a negatively charged protein \(\mathrm{P}^{-x}\)). A solution of this salt was prepared by dissolving  
of this sodium salt of protein in 10g of water and
ebullioscopic analysis revealed that solution boils at
temperature \(6.78 \times 10^{-3}{ }^{\circ} \mathrm{C}\) higher than the normal boiling point of pure water.\(\mathrm{K}_{\mathrm{b}}\)of water of \(0.52 \mathrm{k} \mathrm{~kg} \mathrm{~mol} \mathrm{k}^{-1}\). Also elemental analysis revealed that the salt contain \(1 \%\) sodium metal by weight.
Determine molecular weight of sodium salt of protein.
