2Al (s) + 3Fe(NO3)2 (aq) → 3Fe (s) + 2Al(NO3)3 (aq)

Find the pure amount of iron nitrate solution:

325 g x 87.5% = 284.375 g

Convert 284.375g into mols by dividing by molar mass of the iron nitrate solution

Molar mass of iron nitrate =  55.85 g/mol + 2x14g/mol + 6x16g/mol = 179.85 g/mol

Moles of iron nitrate = 284.375 g / 179.85 g/mol = 1.58

Stoichiometry

3 mols of iron nitrate / 3 mols of iron = 1.58 mols of iron nitrate / x mols of iron

x = 1.58 mols of iron.

Convert that in grams by multiplying by the molar mass of iron

grams of iron = 1.58 mol x 55.85 g/mol = 88.24 g

Setler [38]
The answer is d Thus, the first energy level holds 2 * 1^2 = 2 electrons, while the second holds 2 * 2^2 = 8 electrons. Each orbital. The third energy level can hold up to 18 electrons, meaning that it is not full when it has only electrons.
