A sample of an unknown gas was isolated in a gas containment bulb on a manifold used in this type of work. The volume of the bulb was 1.425 liters. The temperature was 25.40 °C, and the manifold pressure was 583.0 torr. What volume would this gas sample occupy at STP?

Question

Quizplus · Accepted Answer

The correct answer is A because the volume of the gas sample at STP can be calculated using the combined gas law:V1/T1 = V2/T2where V1 is the initial volume, T1 is the initial temperature, V2 is the final volume, and T2 is the final temperature.Plugging in the given values, we get:1.425 L / (25.40 °C + 273.15) = V2 / (0 °C + 273.15)Solving for V2, we get:V2 = 1.000 L
