Insulin is dissolved in suitable solvent and the osmotic pressure (pi) of solution of various concentration (g//cm^(3)) C is measured at 27^(@)C . The slope of plot of pi against C is found to be 4.1 xx 10^(-3) . The molecular mass of inulin is:
Insulin (C_(2)H_(10)O_(5))_(n) is dissolved in a suitable solvent and the osmotic pressure pi of the solution of various concentration ( in kg//m^(3)) is measured at 20^(@)C . The slpe of a plot of pi against c is found to be 8.134xx10^(-3) ( SI units ). The molecular weight of the insulin ( in kg//mol) is :
