🤓 Based on our data, we think this question is relevant for Professor Mandelshtam's class at UCI.
Recall: Graham's Law of Effusion allows us to compare the rate of effusion of two gases. Graham's Law states that the rate of effusion of a gas is inversely proportional to its molar mass.
This means that when comparing two gases:
Recall that rate = volume over time. This means:
Assuming that volumeNe = volumeunk, the equation simplifies to:
Plugging this into the original equation:
A sample of neon effuses from a container in 77 seconds. The same amount of an unknown noble gas requires 157 seconds.
Identify the second gas.
