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
