A hepta peptide of m.wt 529 mu , is made up of glycine [m.wt = 7.5 mu] , Alamine [m.wt=89 mu] and valine [m.wt=117mu] . On hydrolysis gives corresponding amino acids. If the product mixture contains 35.32% of glycine. The sum of alanine and valine molecules in a molecule of hepta peptide is ..............

The colligative properties of electrolytes require a slightly different approach than the one used for the colligative properties of non-electrolytes. The electrolytes dissociate into ions in a solution. It is the number fo solute particles that determines the colligative properties of a solution. The electrolyte solutions, therefore, show abnormal colligative properties. To account for this effect we define a quantity called the van't Hoff factor, given by : i=("Actual number of particles in solution after dissociation")/("NUmber of formula units initially dissolved in solution") i=1 (for non-electrolytes) , i gt 1 (for electrolytes, undergoing dissociation) i lt 1 (for solutes, undergoing association). The molare mass of the solute sodium hydroxide obtained from the measurement of the osmotic pressure of its aqueous solution at 27^(@)C is 25 "g mol"^(-1) . Therefore, its dissociation percentage in this solution is :
