Answer:

0.0072mole

Step-by-step explanation:

Given parameters:

Mass of the compound given = 0.532g

Unknown:

Number of moles = ?

Solution:

To solve this problem, we need to use the expression below:

Number of moles =
(mass)/(molar mass)

Molar mass of Ca(OH)₂ = 40 + 2(16 + 1) = 74g/mol

Number of moles =
(0.532)/(74) = 0.0072mole
