Answer:


\boxed {\boxed {\sf 117.6 \ L \ He}}

Step-by-step explanation:

Regardless of the type of gas, 1 mole at standard temperature and pressure (STP) occupies a volume of 22.4 liters. In this case the gas is helium (He).

We can set up a ratio.


\frac { 22.4 \ L \ He}{ 1 \ mol \ He}

Multiply by the given number of moles.


5.25 \ mol \ He *\frac { 22.4 \ L \ He}{ 1 \ mol \ He}

The moles of helium will cancel.


5.25 *\frac { 22.4 \ L \ He}{ 1 }


5.25 * { 22.4 \ L \ He}

Multiply.


117.6 \ L \ He

5.25 moles of helium gas at STP is 117.6 liters of helium.
