Answer:
Number of moles of Al = 0.02 mol
Number of moles of CuCl₂ = 0.02 mol
Explanation:
Given data:
Mass of CuCl₂ = 2.50 g
Moles of CuCl₂ = ?
Solution:
Formula:
Number of moles = mass / molar mass
Molar mass of CuCl₂ = 63.546 + 35.5 ×2
Molar mass of CuCl₂ = 134.546 g/mol
Now we will put the values in formula:
Number of moles = 2.50 g / 134.546 g/mol
Number of moles = 0.02 mol
Given data:
Mass of Al = 0.50 g
Moles of Al = ?
Solution:
Formula:
Number of moles = mass / molar mass
Molar mass of Al = 27 g/mol
Now we will put the values in formula:
Number of moles = 0.50 g / 27 g/mol
Number of moles = 0.02 mol
