Options
- A. 35.0\ cm ^3
- B. 2.86\ cm ^3
- C. 0.286\ cm ^3
- D. 3.50\ cm ^3
Answer
B. 2.86\ cm ^3
Step-by-step solution
Using Boyle's Law at constant temperature: P_1 V_1 = P_2 V_2 Given P_1 = 1\ atm , V_1 = 10.0\ cm ^3, and P_2 = 3.5\ atm . Substituting the values: 1 10.0 = 3.5 V_2 V_2 = 10.0 3.5 = 2.857\ cm ^3 Rounding to appropriate significant figures, V_2 = 2.86\ cm ^3. Answer: 2.86\ cm ^3
