Question

5 moles of F2 molecules contain how many F atoms

Answer 1

5 moles of F₂ contains $60.110 * 10^{23}$ F⁻ atoms.

Explanation:

To calculate the number of F atoms in F₂, we first calculate the number of F₂ atoms.

Since we know.

1 mole = $6.022 * 10^{23}\ atoms$ (Avagadro's number);

then, 5 mole = $5* (6.022*10^{23} )\ atoms$

= $30.110 * 10^{23}\ atoms.$

There are 2 F ⁻ atoms in one molecule of F₂.

So,

$30.110 * 10^{23}\ atoms\ of\ F_2\ = 2* 30.110 * 10^{23}\ F^- atoms. \\= 60.110 * 10^{23}\ F^- atoms.$
