To find the volume of the gas at STP (Standard Temperature and Pressure, which is 0°C and 1 atm), we can use the combined gas law: $ \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} $. Given: $P_1 = 700 \, \text{torr}$, $V_1 = 8.00 \, \text{L}$, $T_1 = 20.0°C = 293 \, \text{K}$, $P_2 = 760 \, \text{torr}$ (1 atm in torr), $T_2 = 0°C = 273 \, \text{K}$. Solving for $V_2$, we find $V_2 = \frac{P_1V_1T_2}{P_2T_1} = \frac{700 \times 8.00 \times 273}{760 \times 293} \approx 6.87 \, \text{L}$.
