A student has a sample of 1.42 moles of fluorine gas that is contained in a 28.1 L container at 305 K. What is the pressure of the sample?

Respuesta :

Answer:

P = 1.26 atm

Explanation:

Given that,

The number of moles, n = 1.42 mol

Volume, V = 28.1 L

Temperature, T = 305 K

We need to find the pressure of the gas. The ideal gas law is as follows :

[tex]PV=nRT\\\\P=\dfrac{nRT}{V}[/tex]

R = 0.0821 L-atm/mol-K

Put all the values,

[tex]P=\dfrac{1.42 \times 0.0821\times 305 }{28.1 }\\\\P=1.26\ atm[/tex]

So, the pressure of the gas is 1.26 atm.
