Is sand macromolecule or network solid?
you

A macromolecule is a molecule with lots and lots of atoms. (i.e. protein, nucleic acid...)
A network solid is is a chemical compound where the atoms are "bonded by covalent bonds in a continuous network extending throughout the material."
A single grain of sand consists of, on average, ~50,000,000,000,000,000,000 atoms.
That's A LOT.
However, these atoms do bond in network covalent bonds.
But that means it's a covalent network solid.
The short answer is that sand is both a macromolecular substance as well as a covalent network solid, so I would go with it's macromolecular but you can interpret that the way you want.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
