Stoichiometry
The vapour pressure of water is given by, in Psat = A - (5000/T), where A is a constant, Psat is the vapour pressure in atm. and T is the temperature in K.The vapor pressure of water in atm. at 50°C is approximately
Attractive forces between like and unlike molecules are approximately equal
Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
All of these
Sizes of the component molecules are approximately equal
