Posted by Unknown on Tuesday, August 20, 2013 at 3:56pm.

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?

(2.25 L) x (1273.51 kPa / 101.3 kPa) x (0 + 273.15 K) / (12.0 + 273.15 K) = 27.1 L


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?


(1205 cm^3) x (0.00 + 273.15 K) / (-44.0 + 273.15 K) x (0.937 kPa / 101.3 kPa) =
13.3 cm^3




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?
3.
(1300 cm^3) x (0.00 + 273.15 K) / (22.0 + 273.15 K) x (91.9 kPa / 101.3 kPa) =
1091 cm^3
