1. Find out the mass of the gas particle. What type of gas it is?

2. How many moles of gas A particles are sealed in the gas chamber?

The image below is the screenshot of the GasLawSimulator". There is a certain amount of gas A" sealed in the gas chamber. The parameters of gas volume, gas temperature, gas pressure and particle's average rms velocity at current state are all given in the image.
