For pure water at 20 oC:
Po = 17.5 torr
kf = 1.86 oC/m
kb = 0.563 oC/m

1.)What is the boiling point of the solution to the nearest 0.1 oC?

2.)Assume that the molality and molarity of the solution are equal to estimate the osmotic pressure that is developed by the solution at 20.0 oC?

Ok this is a little awkward, but how do you explain chemically the action of cutting, why does it matter if something is sharp? How do elements interact chemically that make things cut or not, cuttable. Why are diamonds the best for cutting? Is cutting the result of a chemical reaction or does it cause a chemical reaction?
