what is the square root of the gram molecular weight of O2 and CO2, (hint: periodic table) and which one will diffuse faster?

Indicate your specific subject in the "School Subject" box, so those with expertise in the area will respond to the question.
The reaction of equation would be the following:

1/2(M1)(V^2)1=1/2(M2)(V^2)2

Sqrt*(M1/M2)=V2/V1

The lighter one will diffuse faster, I believe. But check that by reading about Grams law of effusion, I think.
