Description
Daltonʼs Law of Partial Pressures - total pressure of mixture of gasses is equal to the sum of the individual components - Ptotal P a P +bP c - Ptotal (na +n b + c RT/V - partial pressure - pressures of individual components of gasses a = - mole fraction - amount of moles of part over moles of the whole - Xa= n a n total - partial pressure is x multiplied by total pressure - Pa= x a t - ex. pressure of box is 10 units, whatʼs the pressure of each gas? - 1. solve for mole fraction: total particles = 10 - 4 purple / 10*10 = 4 units - 1 cyan / 10*10 = 1 unit - 3 pink (6 atoms, diatomic, 1 molecule) = 3 / 10*10 = 3 units - given that the total pressure is 30 now... - 4 purple / 10*30 = 12 units - 1 cyan / 10*30 = 3 units - ex. 1.20 atm = 88.6% CH4, 8.9% C2H6, 2.5% C3H8,
