In order to determine the amount of zinc hydroxide substance, you must use the following formula:
n = m / M.
Where n is the amount of zinc hydroxide substance.
m is the mass of zinc hydroxide.
M is the molar mass of zinc hydroxide.
Next, calculate the molar mass of zinc hydroxide using the Periodic Table of Elements.
M (Zn (OH) 2) = 65 + (1 + 16) * 2 = 65 + 34 = 99 g / mol.
Therefore, the molar mass of zinc hydroxide is 99 g / mol.
Next, calculate the amount of zinc hydroxide substance.
n (Zn (OH) 2) = 29 g / 99 g / mol = 0.29 mol.
Therefore, the amount of zinc hydroxide substance is 0.29 mol.
Answer: n (Zn (OH) 2) = 0.29 mol.
