Answer:
The pressure of the gas is 5.8atm.
Explanation:
The information given in the exercise is:
- Number of moles (n): 7.2mol
- Volume of the gas (V): 63.5L
- Temperature of the gas (T): 350°C (623K)
We can use the Ideal Gases formula to calculate the pressure of the gas, replacing the values of n, V and T.
Remember that the units must be always in atm, liters, mol and Kelvin when using the Ideal Gases formula:
[tex]\begin{gathered} P*V=n*R*T \\ P*63.5L=7.2mol*0.082\frac{atm*L}{mol*K}*623K \\ P*63.5L=367.82atm*L \\ P=\frac{367.82atm*L}{63.5L} \\ P=5.8atm \end{gathered}[/tex]So, the pressure of the gas is 5.8atm.
