What are the formula weight of NaCl and BaCl2?

The molecular weight of NaCl is 58.44g/mol, the atomic mass of Na is 22.99 and the atomic mass of Cl is 35.45 when added together we get 58.44 g/mol.The molecular weight of BaCl2 is 208.233g/mol, the atomic mass of Ba is 137.327 and the atomic mass of Cl2 is (35.453)(2) = 70.906 when added together we get 208.233g/mol


Which subatomic particles have mass and re included in the calculation of the atomic mass number?

Protons and neutrons are the subatomic particles that have mass and are included in the calculation of the atomic mass number. Electrons have very low mass compared to protons and neutrons and are usually not included in the atomic mass calculation as they contribute very little to the overall mass of an atom.


What chemical is added to make particles stick together?

A binder or adhesive chemical is typically added to make particles stick together. This chemical helps improve the cohesion and strength of the particles, forming solid structures. Examples include polymers, resins, or clay minerals depending on the application.
