In the given problem, mass of the solute, mass of the solvent and volume of the solution is known. However, only information related to the masses are sufficient to compute the mass percentage of the components.Answer and Explanation:
The acidic peak, K0, K1 and K2 constitute approximately 13%, 60%, 10% and 8% of the intact MAb1, respectively, in terms of the integrated peak area percentage (Fig. 1). The CEX was used to fractionate MAb1 and generate milligram quanti- ties for each of the four charge variants. ...
