Is apple juice a mixture or pure substance?

A pure substance is a substance that is made up of only one type of atom or molecule. For example, gold is a pure substance because it is made up of only gold atoms. Water is also a pure substance because it is made up of only water molecules.

A mixture is a combination of two or more substances that are not chemically combined. For example, apple juice is a mixture of water, sugar, and other compounds. Apple juice is not a pure substance because it is made up of more than one type of molecule.
