Options
- A. 0.1 mole
- B. 0.2 mole
- C. 0.3 mole
- D. 0.4 mole
Answer
B. 0.2 mole
Step-by-step solution
Using the ideal gas equation, PV = nRT Rearranging for the number of moles n, we get n = PV RT Substituting the given values: n = 1.104 10^5 4 10^ -3 2208 n = 441.6 2208 n = 0.2 mole Answer: 0.2 mole
