Answer:
The final pressure of the gas is 0.2 atm
Step-by-step explanation:
The initial pressure, P₁ = 1 atm
The initial volume, V₁ = 1 L
The final volume, V₂ = 5 L
The final pressure, P₂ = ?
Using the Boyle's law equation
P₁ V₁ = P₂ V₂
Substitute P₁ = 1 atm, V₁ = 1 L, and V₂ = 5 L into the equation above
1 x 1 = P₂ x 5
1 = 5P₂
Divide both sides by 5
1/5 = P₂
0.2 = P₂
P₂ = 0.2 atm
The final pressure of the gas is 0.2 atm
