Question

A student has a sample of 1.31 moles of fluorine gas that is contained in a 24.6 L container at 336 K. What is the pressure of the sample? The ideal gas constant is 0.0821 L*atm/mol*K. Round your answer to the nearest 0.01 and include units.

Answer 1

The pressure of the sample is 1.47 atm

Step-by-step explanation

Given:

Moles, n = 1.31 mol

Volume, V = 24.6 L

Temperature, T = 336 K

The ideal gas constant, R = 0.0821 L*atm/mol*K

What to find:

Pressure, P of the sample.

Step-by-step solution:

Pressure, P of the sample can be calculated using the ideal gas equation.

`\begin{gathered} PV=nRT \\ \\ \Rightarrow P=(nRT)/(V) \end{gathered}`

Put the values of the parameters into the formula, we have;

`P=\frac{1.31mol*0.0821\text{ }L.atm/mol.K*336K}{24.6\text{ }L}=1.47\text{ }atm`

The pressure of the sample is 1.47 atm
