Answer:
56.30 kPa
Explanation:
In this case, the pressure of every gas in the mixture is given. Taking the sum of the pressures will give the total pressure of the gas mixture.
Using the Dalton's law of partial pressures, the sum of pressures of each individual gases gives the total pressure of a mixture of gases.
Ptotal= Poxygen + Pnitrogen + Pneon
P-total=20 + 32.1 +4.20 =56.30 kPa
