Question

what is roults law??

Answer 1

Answer:

a law stating that the freezing and boiling points of an ideal solution are respectively depressed and elevated relative to that of the pure solvent by an amount proportional to the mole fraction of solute.

Answer 2

It is a law related to thermodynamics.

• The limiting pressure of a component in a liquid mixture is proportional to its mole fraction in that mixture at constant temperature, according to the concept.
• According to the Raoult’s Law -

• p0 - p/p0 = w × M/ m× W

where -

1. p0 is the vapour pressure of pure water  
2. p is the vapour pressure of solvent  
3. w is the weight of solute  
4. m is the molecular weight of solute  
5. W is the molecular weight of solvent
