Answer:
1.31moles
Explanation:
Given parameters:
Mass of CuO₂ = 125g
Unknown:
Number of moles = ?
Solution:
To solve this problem, we use the expression below:
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of CuO₂ = 63.6 + 2(16) = 95.6g/mol
So;
Number of moles = [tex]\frac{125}{95.6}[/tex] = 1.31moles
