To solve this problem, we use the combined gas law, which is $P_1V_1/T_1 = P_2V_2/T_2$, where $P$ is pressure, $V$ is volume, and $T$ is temperature in Kelvin. First, convert temperatures to Kelvin: $62 °C = 335 K$ and $17 °C = 290 K$. Then, plug in the given values and solve for $V_2$: $795 \text{ torr} \times 4.71 \text{ L} / 335 \text{ K} = 911 \text{ torr} \times V_2 / 290 \text{ K}$. Solving for $V_2$ gives approximately $3.56 L$.
