Answer:
[tex]P_{total}=1.628atm[/tex]
Explanation:
According to dalton theory of partial pressure , partial pressure applied by a component in a mixture of more gas is same as pressure applied when it is taken alone in the container.
And thus [tex]P_{total}=P_A+P_B+P_C[/tex]
and P_A and P_B is given so we need to find P_C for the 3rd gas,
and we will solve by assuming that gas follows the ideality nature of gas,
PV=nRT
P_A=0.177atm
P_B=0.726atm
[tex]P_C \times 7.7L =0.21 \times 0.0821 \times 324[/tex]
[tex]P_C=0.725atm[/tex]
therefore,
[tex]P_{total}=P_A+P_B+P_C[/tex]
[tex]P_{total}=0.177atm +0.726atm + 0.725atm[/tex]
[tex]P_{total}=1.628atm[/tex]
