# Question #c4af6

The Combined Gas Law states that, for an ideal gas, $\frac{P V}{T}$ stays constant, where $P$ is pressure, $V$ is volume, and $T$ is the temperature on an absolute scale.
Under the situation in the question, we substitute values and get $\frac{92.1 \cdot 200}{275} = \frac{3684}{55}$.
In the question, STP refers to a condition of $273.15$ K and 100 kPa.
Now, even if we change temperature and pressure to STP, this still will not change. Thus, $\frac{100 \cdot V}{273.15} = \frac{3684}{55}$. Thus, $V = \frac{3684}{55} \cdot \frac{273.15}{100} \setminus \approx 182.96$ mL.
