Answer:
Explanation:
Given parameters:
Mass of CuCl₂ = 2.50g
Mass of Al = 0.50g
Unknown:
Number of moles of CuCl₂ and Al = ?
Solution:
To solve this problem, we must understand that the number of moles is a fundamental property used in stoichiometry calculations.
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of CuCl₂ = 63.6 + 2(35.5) = 134.5g/mole
Molar mass of Al = 26.98g/mole
Number of moles of CuCl₂ = [tex]\frac{2.5}{134.5}[/tex] = 0.019moles
Number of moles of Al = [tex]\frac{0.5}{26.98}[/tex] = 0.019moles
