Question
____ states that any pure sample of a given compound will contain the same elements in an identical mass ratio.
Answer
The law of constant composition states that any pure sample of a given compound will contain the same elements in an identical mass ratio.
Note: For example, every sample of water will contain two hydrogen atoms for every one oxygen atom, or—in terms of mass—for every one gram of hydrogen, there will be eight grams of oxygen. Even biologically important molecules, such as water and amino acids on Earth are, by composition, the same anywhere else in the universe, even though densities and other physical properties may differ.

Formula unit represents ____.
____ represents the empirical formula of an ionic compound, since they do not form true molecules, rather a coordinated lattice.
____ weight is the term used for ionic compounds "molecular" weight as no molecule actually exists, its just a lattice structure.
____ compounds form from elements of similar electronegativity.
Atomic weight is ____.
____ is a weighted average of the masses of the naturally occurring isotopes of an element, not their weights.
