Question

A gas occupies 3.5 l at 760 mmhg. find the volume of the gas when the pressure is 1140 mmhg

Answer 1

Answer:

1.85l

Explanation:

initial conditions-

pressure= 760mmhg

volume= 3.5l

final conditions-

pressure= ?

volume= 1140mmhg

Therefore according to Boyle' s law,

P1V1= P2V2

760× 3.5= 1140× P2

P2= (760× 3.5) ÷ 1140

=1.847

= 1.85l
