What is the total pressure exerted by a mixture containing four gases if the partial pressures are 43.3 atm, 83.5 atm, 64.2 atm, and 6.3 atm? Solve the the nearest two decimal places.

Answer 1

According to Dalton's Law of partial pressures, the total pressure is just the sum of the pressures of each gas would exert if it were present alone. This means that you would add the partial pressures together:

P_T = 43.3 atm + 83.5 atm + 64.2 atm + 6.3 atm = 197.30 atm
