Question

How to separate butane from a mixture of propane and butane? Option- filtration,diffusion,fractional distillation,simple distillation,crystallisation, chromatography

Answer 1

Answer:

Fractional distillation

Explanation:

Because propane and butane have a near boliling point.

Answer 2

Answer:

Fractional Distillation/ Diffusion

Explanation:

This is because they have different boiling points and the volatile liquid can be collected first followed by the most volatile liquid in this scenario

Since these gases have different molecular masses the lighter molecules will diffuse faster than the heavier molecules
