2.6 One litre of water solution of substance A, which has molecular weight of 125, and substance B, MW = 250, contains 500 mg of A and 1500 mg of B. 1) What are the mass concentrations of A and B in the solution? 2) What are the mole concentrations (molar) of A and B in the solution? If A and B are the only solutes in the solution, 3) What are the mass fractions of A and B in the solutes? 4) What are the molar fractions of A and Bin the solutes?
