How to calculate the molecular weight of ammonium ferrous sulfate?

Ammonium ferrous sulfate is a common chemical that is widely used in water treatment, fertilizer manufacturing, and some chemical reactions. Calculating its molecular weight is the basis for understanding its properties, usage and reaction behavior. In this article, we will introduce in detail how to calculate the molecular weight of ferrous ammonium sulfate, and discuss the calculation method of each step in depth.

1. of Ammonium Ferrous Sulfate

To calculate the molecular weight of ammonium ferrous sulfate, you first need to know its molecular formula. The chemical formula of ammonium ferrous sulfate is ((NH4)2Fe(SO4)2 ), which is composed of four main components: ammonium ion ((NH4 ^ )), iron ion (( Fe ^{2 } )), and sulfate ion (( SO4 ^{2-} )). We will calculate the relative atomic masses of these elements one by one, and then find the molecular weight of ferrous ammonium sulfate.

2. the relative atomic mass

In order to accurately calculate the molecular weight of ammonium ferrous sulfate, we need to look up the relative atomic mass of each element. The following are the relative atomic masses of the main components (in g/mol):

• Nitrogen (( N )):14.01g/mol
• Hydrogen (( H )):1.008g/mol
• Iron (( Fe )):55.85g/mol
• Sulfur (( S )):32.07g/mol
• Oxygen (( O )):16.00g/mol

From these data, we can calculate the mass contribution of each component.

3. Calculating Molecular Weight Steps

In the molecular formula of ammonium ferrous sulfate, we have:

• ( (NH 4) 2 ):2 nitrogen atoms and 8 hydrogen atoms
• ( Fe ):1 iron atom
• ( (SO 4) 2 ):2 sulfur atoms and 8 oxygen atoms

1. Calculate the mass contribution of nitrogen and hydrogen:

• Nitrogen:( 2 \times 14.01=28.02 ) g/mol
• Hydrogen:( 8 \times 1.008=8.064 ) g/mol

2. Calculate the mass contribution of iron:

• Iron:( 1 \times 55.85=55.85 ) g/mol

3. Calculate the mass contribution of sulfur and oxygen:

• Sulfur:( 2 \times 32.07=64.14 ) g/mol
• Oxygen:( 8 \times 16.00=128.00 ) g/mol

4. Summary Molecular Weight

Adding the mass contributions of each element, we get the molecular weight of ammonium ferrous sulfate:

[ 28.02 8.064 55.85 64.14 128.00=284.074 \, \text{g/mol} ]

thus, the molecular weight of ammonium ferrous sulfate is about 284.07g/mol.

5. why calculating ammonium ferrous sulfate molecular weight is important?

Calculating the molecular weight of ammonium ferrous sulfate is very important for chemical reaction, solution preparation and quality control. By knowing its molecular weight, we can:

• Accurate calculation of reaction required ammonium ferrous sulfate
• Control solution concentration
