Question

350 ml of hydrogen gas at 27degreeC exerts 150 mm of hg.if the volume of the gas at 173degreeC is 450 ml what will be its pressure

Answer 1

Answer:

PV=nRT

V∝T

VT

T at constant pressure for a fixed amount of gas.

Initial volume V = 300 ml.

Initial temperature T = 27

o

C =27+273 K = 300 K

Final volume V' = ??.

Final temperature T' =− 8

o

C =273−8 K = 265 K.

300 mL× 265 K =V

′

× 300

V

= 265 ml

Hence, the final volume is 265 ml.
