Applying Osmotic pressureπ $$V=WBMB$$×RTπ$$=WBV$$×RTMB⇒π$$=C$$×RTMB×$$100$$ . . . . (1) While $$C=$$ conc.in $$g/cc$$,$$4=x$$×m . . . . $$(2)Combination$$ equation $$1$$ & $$2Slope=RTMB$$×$$1000$$∴$$MB=RTSlope$$×$$1000=0.0821$$×$$293$$×$$10004.65$$×$$10$$−$$3=5.17$$×$$106$$

Insulin is dissolved in suitable solvent and the osmotic pressure in atm of solutions at various concentration is measured at 20°C. The slope of the plot of p against C is found to be 4.65 × 10^-3. The molecular weight of insulin is 5.17 × 10^x. Then ‘x’ is
