Would it be possible for one mole of a molecule to contain less than 6.02 x 1023 atoms of one of its component elements? For example, could a mole of water have less than 6.02 x 1023 atoms of H? Explain your reasoning.

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

Ijust took the quiz. their is no coefficient needed. : )
