Question #c4af6

Answer 1

The Combined Gas Law states that, for an ideal gas, `(PV)/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 `(92.1*200)/275=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, `(100*V)/273.15=3684/55`. Thus, `V=3684/55*273.15/100\approx182.96` mL.
