Question

the volume of a gas at stp is 250 ml . what volume will it occpy at 300 k and 500 mm hg pressure​

Answer 1

Answer:

Given: P

1

=745 mm Hg

V

1

=250 ml

V

2

=200 ml

∴ By Boyle's law as the temperature is constant.

P

2

=

V

2

P

1

V

1

=

200

745×250

=931.25 mm Hg

Additional pressure required =931.25−745=186.25 mm

Hence, the correct answer is option C.
