A closed beaker contains a mixutre of gases. Their partial pressures are:
Gas A = 2 atm
Gas B = 1 atm
Gas B = 4 atm
What is the total pressure of the gas mixture?

Answer 1

Answer: 7 atm

Explanation:

According to Dalton's Law, the total pressure is the sum of all the individual gas pressures

Hence, Ptotal = P1 + P2 + P3

Since, Gas A = 2 atm

Gas B = 1 atm

Gas B = 4 atm

Ptotal = (2 + 1 + 4) atm

Ptotal= 7 atm

Thus, the total pressure of the gas mixture is 7 atmosphere.
