In deductive reasoning, a hypothesis follows from a set of premises. The premises may be true, in which case the reasoning is sound, or they may be untrue or at least dubious, as in this example.
If gas A has four times the molar mass of gas B, you would expect it to diffuse through a plug:
a. at half the rate of gas B
b. at twice the rate of gas B
c. at a quarter the rate of gas B
