 0.1 mol of propionic acid in 1 kg of water. 
 0.1 mol of fructose in 0.5 kg of water. 
 0.1 mol of HNO3 in 1 kg of water. 

 0.1 mol of Li2SO4 in 1 kg of water.

1000 g water = 1 liter    Osmotic pressure = MRT

0.1 Mol proprionic acid = 0.1 M

0.1 Mol Fructose = 0.2 M

0.1 mol HNO3 is 0.2 M because it dissociates into 2 ions in water.

0.1 Li2SO4 = 0.3 M because it dissociates into 3 ions

RT is the same for all solutions, so we just use increasing molarity for increasing osmotic pressure

proprionic acid, HNO3, fructose, lithium sulfate. Fructose is a larger molecule than HNO3, so it will be more difficult to push thru a membrane. Hope I helped you.
