A 750-mL sample of hydrogen exerts a pressure of 822 torr at 325 K. What pressure does it exert if the temperature is raised to 475 K at constant volume?

Question

We can use the equation for the combined gas law, which states that:

(P1V1)/T1 = (P2V2)/T2

We know that V1 = V2 since the volume is constant, and we can rearrange the equation to solve for P2:

P2 = (P1*T2)/T1

Plugging in the given values, we get:

P2 = (822 torr * 475 K) / 325 K = 1200 torr or 1.20 × 10^3 torr

Therefore, the answer is D.
