Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.
As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.
It does that because petrol is a liquid chemical,has a lower mass per volume,or density,then the water on top so it spread out on top of the water
