Its a solid solution. The mass of 1.4 moles of N 2 is 19.6 g. Osmolarity and Molarity are the same for ionic compounds. 4- Diffusion is the passage of a gas through a tiny orifice into an evacuated chamber. 5- Charles's law, required that the number of moles and the pressure has to be constant in order to get a direct relationship between the temperature and the pressure.
Liquid state is the state of matter at temperature higher than the boiling point.
The B.P of the solution is always higher than the B.P of the solvent. 9- Concentration means decreasing the concentration of the solvent in the solution. 10- Sublimation is the conversion of a liquid state directly to a solid state. Calculate the F.M of a gas that it's density at 300 o K and 0.769 atm. Hg respectively, calculate the partial pressure of water vapor in the wet air.
