Answer:
[tex]20.44\times 10^3 kPa[/tex] is the total pressure of the tank.
Explanation:
Partial pressures of nitrogen = [tex]p_{N_2}=1.61\times 10^4 kPa[/tex]
Partial pressure of oxygen = [tex]p_{O_2}=4.34\times 10^3 kPa[/tex]
Total pressure of gases in the tank = P
Applying Dalton's law of partial pressures :
[tex]P=p_{N_2}+p_{O_2}=1.61\times 10^4 kPa+4.34\times 10^3 kPa[/tex]
[tex]P=20.44\times 10^3 kPa[/tex]
[tex]20.44\times 10^3 kPa[/tex] is the total pressure of the tank.
