## Presentation Description

Explains the relationship between moles and the volume of a gas at STP. Also shows how to use the mole wheel to do mole conversions.

## Presentation Transcript

### Volume of One Mole of Gas:

Volume of One Mole of Gas 1 Mole He How many atoms of helium? 6.02 x 10 23 atoms At 0 °C and 760 mm Hg, 1 Mole of He = 22.4 L Volume = 22.4 L S tandard T emperature and P ressure = STP

### Volume of One Mole of Gas at STP:

Volume of One Mole of Gas at STP He CH 4 N 2 22.4 L 22.4 L 22.4 L 1 mole of ANY GAS = 22.4 L at STP
