Gasoline is a common fuel. most gas stations sell multiple grades of gasoline. these grades are distinguished by their octane content. octane (c8h18) is one of the components of gasoline, which may also contain many other types of hydrocarbons (such as decane, dodecane, and nonane). the fraction of gasoline that is made up of octane affects how the gasoline burns in a car’s engine. higher octane ratings are typically more expensive and can improve performance in certain types of engines. is gasoline a compound or a mixture?

The answer to your question is: Gasoline is a mixture of hydrocarbons.

Explanation:

A mixture is composed by 2 or more compounds.

A compound is a pure substance.

According to the paragraph, gasoline is composed by octane, nonane, decane, dodecane, etc, each of these compounds is different, so gasoline is a mixture of hydrocarbons.

Hydrocarbons are composed only by carbon and hydrogen. we can distinguish them by the number of carbons in their structure.
