Answer:
1.05mol
Explanation:
Given parameters:
Mass of MgCl₂ = 100g
Unknown:
Number of moles = ?
Solution:
The number of moles in a compound can be derived using the expression below:
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of MgCl₂ = 24 + 2(35.5) = 95g/mol
So',
Number of moles = [tex]\frac{100}{95}[/tex] = 1.05mol
