Answer:
Fe=625.026g
Molar mass of Al2O3=102g
Molar mass of Fe=168g
102g of Al2O3-168g of Fe
379.48g of Al2O3-xg of Fe
Cross multiply
102x = 168×379.49
102x=63752.64
X= 625.026g
Therefore,the mass of Fe is 625.027g
Explanation:
Answer:
the first energy level is closest to nuclear the second energy level is a little farther away than the first
1Al2(SO4)3 + 3ZnCl2 → 2AlCl3 + 3ZnSO4
The coefficients represents moles. There is 1 mole of Aluminum Sulfate, 3 moles of Zinc(II) Chloride, 2 moles of Aluminum Chloride, and 3 moles of Zinc(II) Sulfate.
Now add all the coefficients/moles.
9 is the sum of all the coefficients.
