Answer:

The  volume  of  gas  that   exerts   a pressure  of  457.0 mmhg   if  exerted  a  pressure  of  2.50  atm  when  its  volume  was  25.0ml  is  calculated  as follows

 

using

 Bolyes law  formula  

 P1V1=P2V2

P1= 457mmHg

V1=?

P1 =  2.50  atm  =   2.50  x760 =  1900mmHg

V2=  25,0 ml

V1  from the formula  above =  P2V2/P1

=  1900mm hg  x25  ml/  457 mm hg = 104 ml
