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

$\frac{\mathbf{Rate}\mathbf{}\mathbf{Gas}\mathbf{}\mathbf{1}}{\mathbf{Rate}\mathbf{}\mathbf{Gas}\mathbf{}\mathbf{2}}\mathbf{=}\sqrt{\frac{\mathbf{MW}\mathbf{}\mathbf{Gas}\mathbf{}\mathbf{2}}{\mathbf{MW}\mathbf{}\mathbf{Gas}\mathbf{}\mathbf{1}}}$

Since we are talking about ammonia first:
