Do I add sucrose concentration when calculating osmotic pressure with ammonium sulfate?

[moil60]

when calculating the osmotic pressure of a solution with 0.03M ammonium sulfate and 0.04M sucrose...do i need to add the concentration for sucrose?

2 ions of ammonium
1 ion of sulphate

3 x 0.03M = 0.09M

do i need to add the 0.04M ?

thanks

I'm no expert but I think you should add it. As it is not ionized you can just add it. I might be wrong!
