Correct the following samples of gases to standard temperature. (Assume pressure is constant)(STP stands for standard temp and pressure which is 273K and 101.3 kPa, you do not have to think about the pressure for these four but on the last three you will have to so T2 is 273K and on the last three problems for this assignment P2 will be 101.3 kPa)
1. 1622 cm3 at 15.0 oC

2. 12.33 L at 280 K


3. 155.6 dm3 at 110 K 4. 1250 cm3 at -45.0 oC
