Question

4. A gas occupies 1.56 L at 2.00 atm. What will be the volume of this gas if the pressure becomes 4.00 atm?

Answer 1

0.78 L

Step-by-step explanation:

From Boyle's Law :

P₁V₁ = P₂V₂

Here :

• P₁ = 2.00 atm
• V₁ = 1.56 L
• P₂ = 4.00 L

Solving :

• V₂ = P₁V₁ / P₂
• V₂ = 2 x 1.56 / 4
• V₂ = 1.56 / 2
• V₂ = 0.78 L
