12. Daltons Law P t = P 1 + P 2 + P 3 +…….

13. Daltons Law P t = P 1 + P 2 + P 3 +……. P t = x 1 p 1 + x 2 p 2 + x 3 p 3 +……. x = mole fraction p = total pressure

14. Practice – page 177 A sample of natural gas contains 8.24 moles of methane (CH 4 ) 0.421 moles of ethane (C 2 H 6 ) and 0.116 mole of propane (C 3 H 8 ). If the total pressure of the gases is 1.37 atm, what are the partial pressures of the gases
