Answer to Question #281484 in General Chemistry for meow`-`

Question

A gas sample occupies a volume of 15.0 L at 30 ^oC and 750 torr. At what temperature will this gas occupy a volume of 25.0 L at the same pressure? 

Answer 1

volume V1 =12.0 L 

temperature T1 = 25°C = 273 K

 and Pressure = 750 torr.

new volume V2 =15.0 L at 750 torr

temperature T2 = ?

combined gas law says

V1/T1 = V2/T2

T2 = V2 * T1/V1 = 15 L * 273 K/12 L = 341.25 K

Answer

Final temperature = 341 K
