A sealed bottle at 1 atm of pressure holds 1 mole of neon and 1 mole of argon ga

Question

A sealed bottle at 1 atm of pressure holds 1 mole of neon and 1 mole of argon gas at a temperature of 295 K. The curves show the distributions of velocities of the molecules of each gas.

1) Find the number of molecules of argon which have velocities between 200 and 400 (m/s)

2)Find the volume of the bottle

3)In the bottle, vrms of the argon molecules is 429.2 m/s. The temperature is increased by 19.1o deg C, find the new vrms of these molecules.

4)Find the new pressure in the bottle after this increase in temperature (in atm)

Explanation / Answer

Do you think you can upload a picture of the graph?

To find the number of molecules of Argon between 200 - 400 m/s, you would find the total area of the Argon curve that is between 200 and 400.

2. To find the volume, use the equation pV = nRT, and choose a certain point and plug in values to find V.

For 3, 4, account for these changes
