Answer:
The final volume when pressure is changed is 126.1mL
Step-by-step explanation:
Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:
P₁V₁ = P₂V₂
Where P is pressure and V volume of 1, intial state and 2, final state.
Computing the values of the problem:
350mmHg*200mL = 555mmHgV₂
126.1mmHg = V₂
The final volume when pressure is changed is 126.1mL
