Question
The partial pressures of the gases in a mixture are 0.875 atm O2, 0.0553 atm N2, and 0.00652 atm Ar. What is the total pressure of the mixture?A.0.000315 atmB.0.937 atmC.0.813 atmD.0.875 atm
Solution
The total pressure of a gas mixture is the sum of the partial pressures of each individual gas.
So, to find the total pressure, we add up the partial pressures of O2, N2, and Ar:
0.875 atm (O2) + 0.0553 atm (N2) + 0.00652 atm (Ar) = 0.93682 atm
Rounding to three decimal places, the total pressure of the gas mixture is 0.937 atm.
So, the correct answer is B. 0.937 atm.
