🤓 Based on our data, we think this question is relevant for Professor Benson's class at MONTGOMERY COLLEGE.
Which of the gases in the graph below has the largest molar mass?
E) There is not enough information to determine.
We’re being asked which gas has the largest molar mass at 25 ˚C.
In the graph, the y-axis is the relative number of particles while the x-axis is the molecular speed. We can think of the molar mass of a gas as being related to the number of particles (↑ molar mass = ↑ particles).
Recall that the molecular speed of a gas is given by:
where R = gas constant, T = temperature, and M = molar mass of the gas.
