1. Moles and Volume
Conversion

2. The amount of area that a gas can occupy depends on the external pressure and internal temperature.
We use what is call standard temperature and pressure (STP) in order to correctly state the area a gas can occupy.
This area is 22.4 L at STP for any gas substance.
The 2 conversion factors that you will use are:
1 Mol or L
22.4 L Mol

3. How much area does 4.5 moles of hydrogen gas, H2, occupy at STP?
Moles to volume
How much area does 4.5 moles of hydrogen gas, H2, occupy at STP?

4. Moles to volume
If 0.75 moles neon gas, Ne, was placed into a glass tube for a sign, how much area does the tube need to store it at STP?

5. Volume to moles
If an amount of methane gas, CH4, occupied 32.4 L at STP, how many moles of methane are present?

6. Volume to moles
An area of L was occupied by carbon dioxde at STP. How many moles of CO2 were present?
