If we have 10,000 gaseous molecules at 100 °C which exert a pressure of 0.10 atm in a container, then adding another 10,000 gaseous molecules of any substance at the same temperature to the container would increase the pressure to atm.
0.2 atm
0.3 atm
0.4 atm
0.5 atm
Complete the sentence using total, partial, or complete. The pressure that one particular gas exerts when it is part of a mixture of gases is called the pressure of that gas.
