1. A sample of neon is collected at 2.7 atm and 12.0 oC. It has a volume of 2.25 L. What would be the volume of this gas at STP?
2. A sample of argon has a volume of 205 cm3 when its temperature is -44.0 oC and its pressure is 712 mm of Hg. What would be the volume of the argon at STP?
3. A student collects a 3.00 x 102 cm3 sample of hydrogen at 22.0 oC and 91.9 kPa. What volume would the hydrogen occupy at STP?

All of these can be solved using the ideal gas law and its variations. Actually, for these you can use P1V1/T1 = P2V2/T2 where P1 and P2 are initial and final pressures, V1 and V2 are volumes and T1 and T2 are temperatures. Just be careful that you are consistent with your units, and that you always use temperature in Kelvin. You should be able to do these yourself.
