Answer 2

Boyle’s law states that “The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.”This can formulaically written as

P1V1=P2V2

Atmospheric pressure is 1 ATM

hey,

Given volume of gas is 200 ml

New pressure is 5 ATM

Plugging in the values in the formula ,we get

1ATM×200ml=5ATM×χml

χml=1ATM×200ml5ATM

χml=40

χ=40ml
