Question

Consider 1 mole of gas particles at 1.00 Atm and 300 K in a rigid fixed volume container. If another mole of gas particles is added to the container at the same temperature, what would the new pressure be inside of the container?

A) 1 atm
B) 2 atm
C) 0.5 atm
D) 0.25 atm

Answer 1

The new pressure inside the container would be 2.00 Atm.

Step-by-step explanation:

According to Avogadro's Law, at constant temperature and volume, the pressure of a gas is directly proportional to its number of moles. In this case, the initial pressure is 1.00 Atm and the initial number of moles is 1. Adding another mole of gas particles doubles the number of moles, so the new pressure inside the container would also double. Therefore, the new pressure would be 2.00 Atm (option B).
