A neon-dioxygen mixture contains 64 ~g O ₂ and 160 ~g Ne . If the total pressure is 25 bar , calculate the partial pressure of dioxygen.
Options
- A5 bar
- B7.5 bar
- C10 bar
- D20 bar
Correct answer
A. 5 bar
Step-by-step solution
aligned & n _ O ₂ = 64 32 =2 ~mol ; n _ N _ e = 160 20 =8 ~mol & x_ O ₂ = n _ O ₂ n _ Total = 2 2+8 = 2 10 =0.2 & P _ O ₂ =x_ O ₂ P _ Total =0.2 25=5 bar aligned
