A sample of nitrogen (N2) gas in a 10.0L container has a
pressure of 1.0 atm at 297 K. Assuming ideal gas behavior,
what will the pressure be if the same amount of nitrogen
gas is put into a 5.0L container at 297 K?

Respuesta :

Answer: The pressure of nitrogen will be 2.0 atm

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1.0 atm

V = Volume of gas = 10.0 L

n = number of moles = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]297K[/tex]

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{1.0atm\times 10.0L}{0.0820 L atm/K mol\times 297K}=0.41moles[/tex]

Now again using ideal gas equation :

[tex]P=\frac{nRT}{V}=\frac{0.41mol\times 0.0821Latm/Kmol\times 297K}{5.0L}=2.0atm[/tex]

Thus pressure of nitrogen will be 2.0 atm
