Options
- A. 280\ mL
- B. 125\ mL
- C. 100\ mL
- D. 350\ mL
Answer
B. 125\ mL
Step-by-step solution
According to Boyle's law, at constant temperature, P_1 V_1 = P_2 V_2. Given P_1 = 500\ mm Hg , V_1 = 200\ mL , and P_2 = 800\ mm Hg . Substituting the values: 500 200 = 800 V_2 V_2 = 500 200 800 = 125\ mL Answer: 125\ mL
