@contrex,
well, you should use the Osmosic Pressure =MRT
M-Molar
R=8.314kj/mol
T- temperature in Kelvin
so, Molarity=Mol/volume of solvent.
10%= 10g
SCl4 32.1+(35.45 x4)=173.9 g/mol Mol=10g/173.9=0.057504 mol
V- Volume
V=mass/density (remember density is 1.02 g/ml)
V=10g/1.o2g/ml=9.804ml
Temperature= 273K
Molarity=(0.057504 mol) /(9.804 mol/ml) =0.0058654M
Osmosic Pressure=0.0058654M x8.314kj/mol x273k=13.3 KJ
