SOLUTION:

Step 1: List the given values.

[tex]\begin{aligned} & V = \text{30.4 L} \\ & n = \text{6.90 mol} \\ & T = 62^{\circ}\text{C} = \text{335.15 K} \end{aligned}[/tex]

Step 2: Solve for the pressure of the gas by using ideal gas equation.

[tex]\begin{aligned} P & = \frac{nRT}{V} \\ & = \frac{(\text{6.90 mol})\left(0.082057 \: \dfrac{\text{L}\cdot\text{atm}}{\text{mol}\cdot\text{K}}\right)(\text{335.15 K})}{\text{30.4 L}} \\ & = \boxed{\text{6.24 atm}} \end{aligned}[/tex]

Hence, the pressure of the gas is 6.24 atm.
