Answer 1

Answer:

A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. ... Molecular formulas do not indicate how the atoms are arranged in the molecule. The empirical formula tells the lowest whole-number ratio of elements in a compound.
