Problem

How much faster do ammonia (NH 3) molecules effuse than carbon monoxide (CO) molecules?
Enter the ratio of the rates of effusion. Express your answer numerically using three significant figures.
 

Solution

Here, we are dealing with Graham’s law of effusion. We are comparing the rate of two gases. We must find their ratio.

$\frac{Rate\ Gas\ A}{Rate\ Gas\ B}=\sqrt{\frac{MW\ Gas A}{MW\ Gas\ B}}$

Since we are talking about ammonia first:
