Question

Air contains 78.08% nitrogen, 20.095% oxygen, and 0.93% argon. A sample of air occupies 8 L at 273 K and applies a pressure of 2.45 atm to its container. The sample of air is heated to 550 K, at which time it takes up 11.8 L. What is the partial pressure of nitrogen after the air has been heated? A. 2.61 atm B. 261.57 atm C. 282.16 atm D. 1.91 atm

Answer 2

2.61 atm

Option A is the correct option.

Step-by-step explanation:

`(p1 \: v1)/(t1) = (p2 \: v2)/(t2)`

`p2 = (p1 \: v1 \: t2)/(t1 \: v2)`

`p2 = (2.45 * 8 * 550)/(273 * 11.8)`

`p2 = 3.35 \: atm`

Partial pressure of N² :

`3.35 * (78.08)/(100)`

`= 2.61 \: atm`

Hope this helps..
