Determine the number of moles of calcium per mole of calcium hydroxide.

My answer is:
Because there is only one calcium ion per mole of calcium hydroxide, the mole of calcium ion is equal to the mole of calcium hydroxide.

Is this a correct justification?

It is worded oddly, and wrong.

Let me correct it...

Because there is only one calcium ion per formula unit of calcium hydroxide (Ca(OH)2), the number of moles of calcium per mole of calcium hydroxide is one.
