A mixture of three gases, A, B, and C, is
at a total pressure of 7.47 atm. The partial
pressure of gas A is 1.59 atm; that of gas B is
3.78 atm. What is the partial pressure of gas
C?
Answer in units of atm

Answer:

2.1 atm is the partial pressure of gas C.

Explanation:

to calculate partial pressure of gas  C we will use Dalton's law.

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

[tex]P_T=p_{1}+p_{2}+p_{3}...p_{n}[/tex]

where,

[tex]P_T[/tex] = Total pressure

[tex]p_{1}[/tex] = partial pressure of gas-1

[tex]p_{2}[/tex] = partial pressure of gas-2

[tex]p_{3}[/tex] = partial pressure of gas-3

[tex]p_{n}[/tex] = partial pressure of nth gas in the mixture

We have:

[tex]P_T= 7.47 atm [/tex]

[tex]p_{A}=1.59 atm[/tex]

[tex]p_{B}=3.78 atm[/tex]

[tex]p_{C}=?[/tex]

Now put all the given values is expression, we get the partial pressure of the [tex]O_2[/tex] gas.

[tex]P_T=p_{A}+p_{B}+p_{C}[/tex]

[tex]7.47 atm=1.59 atm+3.78 atm+p_{C}[/tex]

[tex]p_{C}=2.1 atm [/tex]

2.1 atm is the partial pressure of gas C.
