Last class, we did a balloon experiment and that it occupies a certain gas which depends on temperature and pressure.
Standard Pressure and Temperature (STP)
0 Degrees Celsius and 101.3 kPa
273k
Standard Ambient Temperature and Pressure (SATP)
25 Degrees Celsius and 100 kPa
298k
- The volume of 1.0 mole of any gas at STP is 22.4L. The molar volume at STP is 22.4L.
22.4L over 1 mol or 1mol over 22.4L ( At STP only)
EXAMPLE: Find the volume occupied by 0.060 mol of CO2 gas at STP.
0.060 mol x 22.4L over 1.0 mol = 1.34L.
