A gear, a lever, and a pulley are simple machines.

This is a picture of a Spirograph. "Spirograph" is the trademarked name of a commercial product sold in toy stores. It's designed to help you draw cool and goofy patterns on paper. It's not a simple machine.

Answer:

No. of Molecules = 18.06 x 10²³ molecules

No. of Atoms of P = 3 atoms

No. of Atoms of Na = 9 atoms

Total No. of Atoms = 24 atoms

Explanation:

FOR NUMBER OF MOLECULES:

$No.\ of\ Molecules = (No.\ of\ Moles)(Avigadro's\ Number)\\No.\ of\ Molecules = (3)(6.02\ x\ 10^{23}\ molecules})\\$

No. of Molecules = 18.06 x 10²³ molecules

FOR NUMBER OF P ATOMS:

$No.\ of\ Atoms\ of\ P = (No.\ of\ Moles)(N.\ of atoms of P)\\No.\ of\ Atoms\ of\ P = (3)(1\ atom})$

No. of Atoms of P = 3 atoms

FOR NUMBER OF Na ATOMS:

$No.\ of\ Atoms\ of\ Na = (No.\ of\ Moles)(N.\ of atoms of Na)\\No.\ of\ Atoms\ of\ Na = (3)(3\ atom})$

No. of Atoms of Na = 9 atoms

FOR TOTAL NUMBER OF ATOMS:

$Total\ No.\ of\ Atoms = (No.\ of\ Moles)(N.\ of\ atoms\ of\ Na + No.\ of\ atoms\ of\ P + No.\ of\ atoms\ of\ O)\\ Total\ No.\ of\ Atoms\ = (3)(3\ atoms + 1\ atom + 4\ atoms}) = (3)(8\ atoms)$
