Which Of The Following Aqueous Samples Has The Lowest Vapor Pressure Above The P

Which of the following aqueous samples has the lowest vapor pressure above the pure liquid? (For ionizing solutes, assume complete ionization, with no ion-pairing.) 

a)  0.4 m NH4NO3                      b)  0.5 m Na2SO4                 c)  0.2 m Ca(NO3)2

d)  0.3 m KCl AND 0.2 m Na2SO4                   e)  pure water

I know that for V.P. the solution with the greatest number of disruption sites will have the lowest V.P. I don’t understand how to find the ions/formula unit. Please explain how to find thay using the examples above.
