If two gases with pressures of 2 atm and 3 atm are mixed at a constant temperature, what will the total pressure be?
2 answers:
If two gases with pressures of 2 atm and 3 atm are mixed at constant temperature, the total pressure will be the sum of the two pressures. Therefore the answer is D. 2 atm + 3 atm or 5 atm will be the total pressure of the gas mixture.
Answer:
D. 2 atm + 3 atm
Explanation:
Given:
Pressure Gas 1 = 2 atm
Pressure Gas 2 = 3 atm
Explanation:
As per Dalton's Law in a mixture of gases, the total pressure is the sum of the partial pressures of the individual gases.
Ptotal = P1 + P2 + P3 + ...
where P1, P2,P3 are the partial pressures
Therefore for the given gas mixture, the total pressure would be:
Ptotal = 2 atm + 3 atm = 5 atm
