Question

20/40 which would have more atoms? 1 mole of si 1 mole of au 1 mole of li none, all are equal

Explanation:

Step1: Recall Avogadro's Number

Avogadro's number ($N_A$) is approximately $6.022\times10^{23}$ particles (atoms, molecules, ions, etc.) per mole.

Step2: Analyze Moles of Atoms

For any substance, 1 mole of that substance contains $N_A$ number of particles (in this case, atoms, since Si, Au, and Li are all elements). So, 1 mole of Si, 1 mole of Au, and 1 mole of Li each contain $6.022\times10^{23}$ atoms.

Answer:

None, all are equal
