One mol of a pure substance contains 6.0221367 x 10^23 particles according to Avogadro's number.
A perfect vaccuum is pure space and has no particles in it
It would be a mixture of various minerals and chemicals if any were present in the water before evaporation

The number of Avogadro is 6,022 140 857(74).10e23.
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
pure substance
No, a suspension is not a pure substance. It is a mixture of particles dispersed in a liquid, where the particles are not fully dissolved and can be seen with the naked eye.
Even if the apple juice is labelled as '100% pure', it is still a mixture of water particles, sugar particles, flavour particles, and vitamin particles. So it is a mixture, not a pure substance.
A pure substance by definition cannot be a mixture. Pure in chemistry means only one substance is present.
An element.
If it is a pure substance, than only one! Now that pure substance may contain many different elements (as many elements can make up a single pure compound), but a pure substance means only one compound.
A heterogeneous mixture with one substance present and two phases present is a suspension. In a suspension, the particles of one substance are physically mixed in another substance but are not dissolved, resulting in two separate phases. Examples include sand in water or oil in water.
ocean water is not a pure substance because it has to particles salt and water so there for it does not have a1 particle so it is a pure substance
A pure substance is a substance that cannot be separated by physical means. To determine whether a substance is pure, let a container of it evaporate. If there is no residue then the substance is pure.
It tells you the elements and the proportions of those elements that are present to make the pure substance.
