if 0.00531 mol N2O effuses through an orifice in a certain period of time, how many moles of N2O3 would effuse in the same time under the same conditions?

Question

aaronq · Answer

use grahams law of diffusion

anonymous · Answer

How though? I know that the rate of two things divided is equal to the inverse square root of the molar masses but how do I apply that?

aaronq · Answer

when you find the ratio of their rates of diffusion apply that.  say the rate of $\dfrac{N_2O}{N_2O_3}$ is $\dfrac{2}{1}$, then just make them equal to each other.  

 $\dfrac{N_2O}{N_2O_3}=\dfrac{2}{1}\rightarrow\dfrac{0.00531mol }{n_{N_2O_3}}=\dfrac{2}{1} \rightarrow  n_{N_2O_3}=0.002655 mol$
