Here are 3 main types of models are ( Physical, Mathematical, and Conceptual. Models have limitations but are useful and can be changed based on a new evidence.
<span>for every 1 mole of Cu3(PO4)2, there are 2 moles of phosphorus. We also know that 1 mole of Cu3(PO4)2 has 6.022 x 10^23 atoms (Avogadro's number

Saponification is the hydrolysis of fats or oils under basic conditions to afford glycerol and the salt of the corresponding fatty acid. ... It is important to the industrial user to know the amount of free fatty acid present, since this determines in large measure the refining loss.
Lewis structures show the bonding between atoms of a molecule and the lone pairs that may exist in the molecule.
