Equal weight of CO and CH ₄ are mixed together in an empty container at 300 ~K . The fraction of total pressure exerted by CH ₄ is
Options
- A16 17
- B7 11
- C8 9
- D5 16
Correct answer
B. 7 11
Step-by-step solution
Let the weight of CO = weight of CH ₄=a ~g Moles of CO = a 28 Moles of CH ₄= a 16 Total moles = a 28 + a 16 x_ CH ₄ = a 16 a 28 + a 16 = a 16 28 16 44 a = 14 22 = 7 11 Fraction of pressure exerted by CH ₄=7 / 11 .
