The volume of a balloon occupied by a certain gas depends on the temperature and pressure.
Standard Pressure & Temperature (STP)
* 0°C & 101.3 kPa
(273 K)
Standard Ambient Temperature & Pressure (SATP) (24.8L/mol)
* 25°C & 100kPa
* 25°C & 100kPa
(298 K)
The volume of 1.0 mole of any gas at STP is 22.4
The molar volume at STP is 22.4L
Example
1) Find the volume occupied by 0.060 mol of CO2 gas at STP
2) Find the number of moles in a 264.0 mL sample of NO2 at 0° and 101.3 kPa(STP)
3) Find the volume occupied by 22.0g of CO2 (g) at STP
I'm very impressed with the way you added the formulas! They look really good, and its very easy to follow. Excellent work.
ReplyDeleteWhen your typing up your future summaries, try and include examples that you make up on your own. Don't just copy the ones we did in class. Change the chemical formula, the number of moles or the grams; or something else. Just make it your own.
