a. "one mole of any substance has 6.022x10²³ atoms, molecules or ions (Avogadro's number) into it"

b. $\frac{1mol}{6.022x10^{23}atoms/molecules/ions}$ and $\frac{6.022x10^{23}atoms/molecules/ions}{1mol}$

• $\frac{6.022x10^{23}atomsAl}{1molAl}$

• $\frac{1molAu}{6.022x10^{23}atomsAu}$

Explanation:

Hello,

a. In this case, a plausible statement would be: "one mole of any substance has 6.022x10²³ atoms, molecules or ions (Avogadro's number) into it".

b. Now, the possible conversion factors could be:

$\frac{1mol}{6.022x10^{23}atoms/molecules/ions}$

or conversely:

$\frac{6.022x10^{23}atoms/molecules/ions}{1mol}$

• Moles Al from atoms Al: the conversion factor will be:

$\frac{6.022x10^{23}atomsAl}{1molAl}$

Since we will need to simplify moles to get atoms.

• Atoms Au from mol Au: the conversion factor will be:

$\frac{1molAu}{6.022x10^{23}atomsAu}$

Since we will need to simplify atoms to get moles.

Best regards.
