I believe the correct answer is false.
Decomposition and synthesis is the answer
The question says only to convert the Zn(OH)₂ into moles. But the given answer has many errors such as formula, mass and moles.
<span>The corrected answer is as follows.
</span>Moles (mol) = mass (g) / molar mass (g/mol)
<span>
</span><span>Mass of Zn(OH)₂</span><span> = 0.45 g
Molar mass of Zn(OH)₂ = </span><span>99.424 g/mol
</span>Hence, moles of Zn(OH)₂ = 0.45 g / 99.424 g/mol
<span> = 4.526 x 10⁻³ mol
