The Effect of Relative Molecular Mass
Chemistry: Cambridge International GCSE Supplement, topic 1.2.2
Test yourself on The Effect of Relative Molecular Mass
Which of these will mean a faster rate of diffusion?
As molecular mass increases, the rate of diffusion...
Molecular Mass and Diffusion
When ammonia gas and hydrogen chloride gas react, where does the resultant white ring form? (Hydrogen chloride has a higher molecular mass.)
In the experiment to investigate the effect of molecular mass on diffusion, why does the white ring form nearer the hydrochloric acid?
