Respuesta :
The total pressure of the flask is sum of partial pressures of the gases present in a mixture of gas
This is Dalton's law of partial pressures .'
say we have a mixture of "n" gases with respective pressure : P1, P2 ...Pn
total pressure of the gases = P1 +P2 + P3 + ...Pn = Ptotal
So in the given problem the total pressure of flask will be = 0.72+1.65 = 2.37 atm
2.37 atm is the total pressure in the flask when a 20.0-litre flask contains a mixture of argon at 0.72 atmospheres and oxygen at 1.65 atmospheres.
What is an ideal gas equation?
The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
The total pressure of the flask is the sum of partial pressures of the gases present in a mixture of gas. This is Dalton's law of partial pressures.
The total pressure of the gases = [tex]P_1 +P_2 + P_3 + ...P_n = P_{total}[/tex]
So in the given problem, the total pressure of the flask will be = 0.72+1.65 = 2.37 atm
Hence, 2.37 atm is the total pressure in the flask when a 20.0-litre flask contains a mixture of argon at 0.72 atmospheres and oxygen at 1.65 atmospheres.
