The volume is $68.1 \setminus \text{L}$ at $\text{STP}$.

#### Explanation:

Well, assuming that the hydrogen gas is contained at $\text{STP}$, then the molar volume would be $22.7 \cdot 3 = 68.1 \setminus \text{L}$.

Due to the new conditions of $\text{STP}$, the new molar volume using the ideal gas equation $\left(P V = n R T\right)$ comes out as $22.7 \setminus \text{L}$.

So, $3$ moles of hydrogen gas at $\text{STP}$ will have a molar volume of

$3 \textcolor{red}{\cancel{\textcolor{b l a c k}{\text{mol"*(22.7 \ "L")/(color(red)cancelcolor(black)"mol")=68.1 \ "L}}}}$.
