Formulas for this assignment V1/T1=V2/T2                  and               V1T2P1=V2T1P2

1.  What volume will a sample of hydrogen occupy at 128.0 oC if the gas occupies a volume of 2.23 dm3 at a temperature of 0.0 oC?   Assume that the pressure remains constant.  (remember to change to Kelvin).

2.  If a gas occupies 1733 cm3 at 10.0 oC, at what temperature will it occupy 950 cm3?  Assume that pressure remains constant.

3.  A gas occupies 1560 cm3 at 285 K.  To what temperature must the gas be lowered to, if it is to occupy 25.0 cm3?  Assume a constant pressure.

 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

 Combined Gas Law Calculations 1.  A sample of neon is collected at 1273.51 kPa 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 1205 cm3 when its temperature is -44.0 oC and its pressure is .937 kPa.  What would be the volume of the argon at STP? 3.  A student collects a 13.00 x 102 cm3 sample of hydrogen at 22.0 oC and 91.9 kPa.  What volume would the hydrogen occupy at STP?
