$V = 17 L$

#### Explanation:

AT STP conditions the pressure is $P = 1 a t m$ and the temperature is $T = 273 K$.

Assuming that the gas behaves ideally, we can use the ideal gas law:

$P V = n R T$

To fin the volume, we can rearrange the ideal gas law expression in terms of volume:

$\implies V = \frac{n R T}{P} = \frac{0.75 \cancel{m o l} \times 0.082 \frac{\cancel{a t m} \cdot L}{\cancel{K} \cdot \cancel{m o l}} \times 273 \cancel{K}}{1 \cancel{a t m}} = 16.79 L \cong 17 L \left(\textcolor{b l u e}{\text{2 sig. figures}}\right)$.
