Options
- A. 3.11 dm^3
- B. 0.66 dm^3
- C. 0.11 dm^3
- D. 3.5 dm^3
Answer
B. 0.66 dm^3
Step-by-step solution
Using the combined gas equation: P_1 V_1 T_1 = P_2 V_2 T_2 Given: P_1 = 2 atm V_1 = 0.35 dm^3 T_1 = 290 K At STP: P_2 = 1 atm T_2 = 273 K Substituting the values: 2 0.35 290 = 1 V_2 273 V_2 = 2 0.35 273 290 V_2 = 191.1 290 0.66 dm^3 Answer: 0.66 dm^3
