Ammonia (M = 17 g/mol) and hydrogen chloride (M = 36.5 g/mol) are released at the same time at the same temperature at one end of a long tube. Find the ratio of their rms speeds,$\frac{v_{N{H}_3}}{v_{HCl}}$(two decimals). (Diffusion in air is slower than this, but the ratio indicates which moves faster.)
