Consider separate solutions of 0.500M C2H5OH(aq), 0.100 M Mg3(PO4)2(aq), 0.250M KBr(aq) and 0.125M Na3PO4(aq) at 25oC. Which statement is true about these solutions, assuming all salts to be strong electrolytes ?


(1) 0.100 M Mg3(PO4)2(aq) has the highest osmotic pressure

(2) 0.125 M Na3PO4(aq) has the highest osmotic pressure

(3) 0.500 M C2H5OH(aq) has the highest osmotic pressure.

(4) They all have the same osmotic pressure
