The partial pressure of gas B is 5.2 atm.
What do you understand by partial pressure?
When more than one gas is present in a container, each gas exerts pressure, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.
Let there be n different gases in the mixture, each at a different pressure (P1, P2, etc.)
Then the total pressure will be:
[tex]P_{total}[/tex] = ∑[tex]P_{1}[/tex] + [tex]P_{2}[/tex] + [tex]P_{3}[/tex]
Now, partial pressure of mixture of gas containing gas A = [tex]P_{A}[/tex]
partial pressure of mixture of gas containing gas B = [tex]P_{B}[/tex]
Total pressure of gas = 5.60 atm
Pressure of gas [tex]P_{A}[/tex] = 0.40 atm
[tex]P_{total}[/tex] = [tex]P_{A}[/tex] + [tex]P_{B}[/tex]
5.60 atm = 0.40 atm + [tex]P_{B}[/tex]
[tex]P_{B}[/tex] = 5.60 - 0.40 = 5.2 atm
So, the partial pressure of gas B is 5.2 atm.
