Answer:
0.0072mole
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 = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of Ca(OH)₂ = 40 + 2(16 + 1) = 74g/mol
Number of moles = [tex]\frac{0.532}{74}[/tex] = 0.0072mole
