Answer :
Final answer:
The total pressure of the gas mixture is found by adding the partial pressures of all the gases, resulting in a total pressure of 13.78 kPa.
Explanation:
To find the total pressure of a mixture of gases, according to Dalton's Law of Partial Pressures, we simply add together the partial pressures of the individual gases. For the given partial pressures of 5.0 kPa, 4.56 kPa, 3.02 kPa, and 1.20 kPa, we calculate the total pressure as follows:
Ptot = P1 + P2 + P3 + P4
Ptot = 5.0 kPa + 4.56 kPa + 3.02 kPa + 1.20 kPa = 13.78 kPa
Therefore, the total pressure for the mixture of the four gases is 13.78 kPa.
