Question

The pressure exerted on a 240 ml sample of hydrogen gas at constant temperature is increased from 325 mmhg to 550 mm hg, what will be the final volume of the sample

Answer 1

The  final  volume  of  the  sample  is calculate  using  boyles  law  formula 
that  is  P1V1=P2V2
V1 =  240  ml
P1= 325  nmmhg
P2=550  mmhg
V2=?
from  the  formula  above   V2  = P1V1/P2
=  240ml  x325mmhg /550  mmhg =   141.8 ml
