Consider separate solutions of `0.500 M C_(2)H_(5)OH(aq)`,`0.100 M Mg_(3)(PO_(4))(aq)`,`0.250 M KBr(aq)`, and `0.125 M Na_(3)PO_(4)(aq)` at `25^(@)C`. Which statement is true about these solutions, assuming all salts to be strong electrolytes?

Options

A. `0.500 M C_(2) H_(5)OH(aq)` has the highest osmotic pressure
B. They all have the same osmotic pressure
C. `0.100 MM g_(3)(PO_(4))_(2)(aq)` has the highest osmotic pressure
D. `0.125 M Na_(3)PO_(4)` (aq) has the highest osmotic pressure

Explanation

`0.5 M C_(2)H_(5)OHimpliespi =0.5 RT`
`0.1 M Mg_(3)(PO_(4))_(2)impliespi=iCRT=(5xx0.1)RT=0.5RT`
`0.250M Kbrimpliespi=iCRT=(2xx0.250)RT=0.5RT`
`0.125M Na_(3)PO_(4)impliespi=iCRT=(4xx0.125)RT=0.5RT`
