Given $1$ mole is equal to $6\mathrm{.}023{10}^{23}$ particles, how many sodium ions are present when $2$ moles of sodium chloride is mixed with $4$ moles of sodium oxide?

Hint: Write out the chemical formula for each compound to find out moles of ions.

$6\mathrm{.}0{10}^{24}$

$5\mathrm{.}4{10}^{24}$

$4\mathrm{.}8{10}^{24}$

$3\mathrm{.}6{10}^{24}$

Too many to count
