At constant temperature, a gas occupies a volume of 200 mL at a pressure of 500 mm Hg. What will be its volume at 800 mm Hg pressure?

Step-by-step solution

According to Boyle's law, at constant temperature, P₁ V₁ = P₂ V₂ . Given P₁ = 500 mm Hg , V₁ = 200 mL , and P₂ = 800 mm Hg . Substituting the values: 500 200 = 800 V₂ V₂ = 500 200 800 = 125 mL Answer: 125 mL
