calculate number of grams of iron in one mole of ferrous ammonium sulfate.hint how many moles are in one mole of ferrous ammonuim sulfate?
moles ferrous ammonium sulfate = grams/molar mass.
Then number of moles Fe in the compound x # mols.
To calculate the number of grams of iron in one mole of ferrous ammonium sulfate, we first need to find the molar mass of ferrous ammonium sulfate.
The formula for ferrous ammonium sulfate is (NH4)2Fe(SO4)2 · 6H2O. Let's calculate its molar mass step by step:
1. Molar mass of (NH4)2Fe(SO4)2:
- Molar mass of 2x NH4 = 2x (14.01 g/mol) = 28.02 g/mol
- Molar mass of Fe = 55.85 g/mol
- Molar mass of 2x SO4 = 2x (32.07 g/mol) = 64.14 g/mol
Adding these together: 28.02 g/mol + 55.85 g/mol + 64.14 g/mol = 147.01 g/mol
2. Molar mass of 6H2O:
- Molar mass of 6x H2O = 6x (18.02 g/mol) = 108.12 g/mol
Adding the molar masses of (NH4)2Fe(SO4)2 and 6H2O:
147.01 g/mol + 108.12 g/mol = 255.13 g/mol
Now, we know that one mole of ferrous ammonium sulfate has a molar mass of 255.13 g/mol. Since the formula indicates that there is one mole of iron in one mole of ferrous ammonium sulfate, we can conclude that the molar mass of iron is 55.85 g/mol.
Therefore, there are 55.85 grams of iron in one mole of ferrous ammonium sulfate.
To calculate the number of grams of iron in one mole of ferrous ammonium sulfate, we first need to find out how many moles of iron are present in one mole of ferrous ammonium sulfate.
The formula for ferrous ammonium sulfate is (NH4)2Fe(SO4)2·6H2O. From the formula, we can see that there is one iron (Fe) atom in one mole of ferrous ammonium sulfate.
To calculate the molar mass of ferrous ammonium sulfate, we need to add up the atomic masses of all its constituent elements. The atomic masses for nitrogen (N), hydrogen (H), sulfur (S), and oxygen (O) can be found in the periodic table. For iron (Fe), the atomic mass is 55.85 g/mol.
(NH4)2Fe(SO4)2·6H2O:
2(N) + 8(H) + 2(Fe) + 2(S) + 8(O) + 12(H2) + 6(O) =
28 + 8 + 111.7 + 32 + 128 + 24 + 6 = 337.7 g/mol
Now that we know the molar mass of ferrous ammonium sulfate is 337.7 g/mol, we can use this information to calculate the number of grams of iron in one mole.
Since there is one iron atom in one mole of ferrous ammonium sulfate, the number of grams of iron in one mole is equal to the molar mass of ferrous ammonium sulfate (337.7 g/mol).
Therefore, there are 337.7 grams of iron in one mole of ferrous ammonium sulfate.
