How many formula units are in a mole of Mg(OH)_(2) ? (Use 2 decimals, in correct Scientific Notation)Answer: square times 10square power. Each formula unit would contain square atom of magnesium. square atoms of oxygen, and square atoms of

To determine the number of formula units in a mole of $Mg(OH)_{2}$, we need to use Avogadro's number, which is $6.022 \times 10^{23}$ formula units per mole.<br /><br />Step 1: Calculate the number of formula units in a mole of $Mg(OH)_{2}$.<br />Number of formula units = Avogadro's number<br />Number of formula units = $6.022 \times 10^{23}$<br /><br />Step 2: Determine the number of atoms of magnesium, oxygen, and hydrogen in each formula unit of $Mg(OH)_{2}$.<br />Each formula unit of $Mg(OH)_{2}$ contains:<br />- 1 atom of magnesium<br />- 2 atoms of oxygen<br />- 2 atoms of hydrogen<br /><br />Therefore, the final answer is:<br />There are $6.02 \times 10^{23}$ formula units in a mole of $Mg(OH)_{2}$. Each formula unit contains 1 atom of magnesium, 2 atoms of oxygen, and 2 atoms of hydrogen.
