Consider separate solutions of 0.500 M C2H5OH(aq), 0.100 M Mg3(PO4)2(aq),0.250 M KBr(aq) and 0.125 M Na3PO4(aq) at 250C.Which statement is true about these solutions, assuming all salts to be strong electrolytes ?
They all have the same osmotic pressure.
0.100 M Mg3(PO4)2(aq) has the highest osmotic pressure.
0.125 M Na3PO4(aq) has the highest osmotic pressure.
0.500 M C2H5OH(aq) has the highest osmotic pressure.
