The volume of the oxygen gas at standard temperature is 41.36 liters.
The given parameters;
The volume of the oxygen gas at standard temperature is determined by applying Charles law as shown below;
[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2} \\\\V_2 = \frac{V_1 T_2}{T_1} \\\\V_2 = \frac{45 \times 273}{297} \\\\V_2 = 41.36 \ L[/tex]
Thus, the volume of the oxygen gas at standard temperature is 41.36 L.
