Answer:
Use a separating funnel since the petrol floats above the water. Just let the mixture stand.
Petrol and water are not soluble, so they will eventually separate. Since the petrol is lighter than the water, it will form a layer on top, and may be drawn off.

Answer:
we can separate the following mixture using distillation.
as the difference between the boiling point of gasoline (483 K ) and of water ( 373 K) is high.
after separating the gasoline and water the residue left will be salt in the container.
( for separating gasoline and saltwater, separating funnel can also be used, after both are separated, using distillation we can separate salt from water. )
