Problem

Which of the gases in the graph below has the largest molar mass?

A) A

B) B

C) C

D) D

E) There is not enough information to determine.

Solution

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.
