<h3>Solution:</h3>

$\text{mass of Pb = 1.15 × 10²⁴ Pb atoms} × \frac{\text{1 mol Pb}}{\text{6.022 × 10²³ Pb atoms}} × \frac{\text{207.2 g Pb}}{\text{1 mol Pb}}$

$\boxed{\text{mass of Pb = 396 g}}$

Answer:

See explanation

Explanation:

The word equation is just a statement of the reaction in words as follows;

Magnesium oxide ----> Magnesium metal + oxygen gas

An unbalanced stoichiometric equation doesn't have equal number of atoms of each element on both sides.

Hence the unbalanced stoichiometric equation is as follows;

MgO(s) -----> Mg(s) + O2(g)
