SOLUTION:

Step 1: List the given values.

[tex]\begin{aligned} & P = \text{9.4 atm} \\ & n = \text{5.6 mol} \\ & T = 128^{\circ}\text{C} = \text{401.15 K} \end{aligned}[/tex]

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

[tex]\begin{aligned} V & = \frac{nRT}{P} \\ & = \frac{(\text{5.6 mol})\left(0.082057 \: \dfrac{\text{L}\cdot\text{atm}}{\text{mol}\cdot\text{K}}\right)(\text{401.15 K})}{\text{9.4 atm}} \\ & = \boxed{\text{19.6 L}} \end{aligned}[/tex]

Hence, the volume of the gas is 19.6 L.
