To what pressure must a gas be compressed in order to get into a 3.00 cubic foot tank
the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure?

101333.33mmHg

Explanation:

The following were obtained from the question:

P1 = at stp = 760mmHg

V1 = 400.0cu.ft

V2 = 3cu.ft

P2 =?

Using Boyle's law equation, we obtained:

P1V1 = P2V2

760 x 400 = P2 x 3

Divide both side by the 3

P2 = (760 x 400) /3

P2 = 101333.33mmHg

The gas must b compressed to a pressure of 101333.33mmHg
