At 570.mmHg and 25 °C,a gas sample has a volume of 2270 mL.What is the final pressure (in mmHg)at a volume of 1250 mL and a temperature of 175 °C,if the amount of gas does not change?

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 all temperatures to Kelvin: $25°C = 298K$ and $175°C = 448K$. Then, plug in the given values: $(570 \, mmHg \times 2270 \, mL) / 298K = (P_2 \times 1250 \, mL) / 448K$. Solving for $P_2$ gives $P_2 = 1560 \, mmHg$.
