Using Raoult's law or Henry's law for each substance (whichever one you think appropriate), calculate the pressure and gas-phase composition (mole fractions) in a system containing a liquid that is 0.3 mole% N2 and 99.7 mole% water in equilibrium with nitrogen gas and water vapor at 80C.
CH 111 Notes: Week 1 Chapter 1: Matter and Energy Matter: anything that has mass and occupies space (different than weight) Pure substance: substance that cannot be separated by physical processes (ex. water) o Element: cannot be decomposed into a smaller subunit (ex. Na- Sodium) o Compound: can be decomposed by chemical processes (ex. table salt) Mixture: 2 or more pure substances, can be separated by physical processes (ex. oil and water) o Heterogeneous: you are able to distinguish between the different components (ex. sand in water) o Homogeneous: You are unable to distinguish between the components, has a uniform composition, aka a solution (ex. salt wate
