Question

a gas occupies a volume of 250 cm^3 at 745 torr and 25°C. what additional pressure is required to reduce the gas volume to 200 cm^3 at the same temperature?

Answer 1

p1v1=p2v2
0.98×250=200×v2
v2=1.225

Answer 2

Answer:

186.25

Explanation:

We know that

P1V1=P2V2

torr is just a unit of pressure.

P1=745 torr

V1=250 cm^3

V2=200 cm^3

So,

745*250=P2*200

P2=931.25

Hence, the additional pressure that is required is

931.25-745

=186.25
