What is the osmotic pressure in #"mm Hg"# of a solution of #"45.0 g"# ribose dissolved into #"800.0 g"# of water at #40^@"C"#? Assume the density is #"1.00 g/mL"#. #MW = "150.13 g/mol"#
The osmotic pressure is given by:
where:
and it is the pressure required to stop the flow of solvent through a semi-permeable membrane from low to high concentration.
Thus, the osmotic pressure is (assuming the solution volume doesn't change, which is completely unreasonable!!):

We assume that the ribose is involatile..........
Now the vapour pressure exerted by a solution is proportional to the mole fraction of the volatile component........

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
