ANSWER
The volume of the gas in liters is 2.016 Liters
STEP-BY-STEP EXPLANATION:
Given parameters
The mole of the given gas = 0.090 mole
Recall that, 22.4L is equivalent to 1 mole at S.T.P
Let x be the volume of the gas in Liters
[tex]\begin{gathered} 22.4\text{ L }\rightarrow\text{ 1 mole} \\ x\text{ L }\rightarrow\text{ 0.090 mole} \\ \text{Cross multiply} \\ 22.4\cdot\text{ 0.090 = 1 }\cdot\text{ x} \\ x\text{ = 22.4 }\cdot\text{ 0.090 } \\ x\text{ = 2.016 Liters} \end{gathered}[/tex]Therefore, the volume of the gas in liters is 2.016 Liters
