Question

A 34.4 L sample of oxygen gas at 229°C and 752 torr is cooled to 34°C at 668 torr. The volume of the sample is now

L.

Answer 1

23.55 L

Step-by-step explanation:

USe the following 'identity' of gs laws

P1 V 1 / T1 = P2 V2 / T2 ( T must be in Kelvin)

re arrange to

P1 V 1 T2 / (T1 P2) = V2 NOW SUB IN THE VALUES

752 * 34.2 * ( 34 + 273.15) / [( 229 + 273.15) * 668] = V2 = 23.55 L
