Answer :
Answer:
0.64 atm
Explanation:
Partial pressure is defined as the pressure of an individual gas in a mixture. Thus, the total pressure of an ideal gas mixture is the sum of the partial pressures of the gases.
As in the problem you have three gases with pressures of 0.30 atm, 0.16atm and 0.18atm the pressure of the gas mixture is:
0.30atm + 0.16atm + 0.18atm = 0.64 atm
