He gas
initial final
P1 = 1657pi P2 =
V1 = 5.25L V2 = 5.25 L
P1V1 = P2V2
P2 = P1V1/V2
= 1657*5.25/5.25 = 1657psi
The pressure of helium = 1657psi
O2 gas
initial final
P1 = 440.4pi P2 =
V1 = 5.25L V2 = 5.25 L
P1V1 = P2V2
P2 = P1V1/V2
= 440.4*5.25/5.25 = 440.4psi
The pressure of oxygen =440.4psi
The total pressure of gases mixture in the tank = 1657 + 440.4 = 2097.4psi >>>>answer
