Question

coffee is a mixture or pure substance ?​

Answer 1

Answer:

It is composed only of water molocules, all of which are identical. Real world non-polluted fresh water has some other substances in it, but the vast majority of particles are still water molocules, so for most purposes its fine to regard it as a pure substance. ... So coffee is not a pure substance.
