Introduction:
Mohr's salt, also known as ammonium iron(II) sulfate, is a chemical compound with the formula (NH4)2Fe(SO4)2·6H2O. It is a double salt that contains ammonium ions (NH4+) and iron(II) ions (Fe2+). When Mohr's salt dissociates, it releases these ions into solution. In this response, we will discuss the number of moles produced on the dissociation of Mohr's salt and explain the process in detail.

Dissociation of Mohr's Salt:
When Mohr's salt is dissolved in water, it dissociates into its constituent ions, ammonium (NH4+) and iron(II) (Fe2+), along with sulfate ions (SO4^2-):
(NH4)2Fe(SO4)2·6H2O → 2NH4+ + Fe2+ + 2SO4^2- + 6H2O

Calculating the Number of Moles:
To calculate the number of moles produced on the dissociation of Mohr's salt, we need to know the amount of Mohr's salt present in the given sample. This can be determined using the formula:

Number of moles = Mass / Molar mass

1. Mass of Mohr's salt:
The mass of Mohr's salt can be determined by weighing the sample on a balance. Let's assume the mass of Mohr's salt is given as 'm' grams.

2. Molar mass of Mohr's salt:
The molar mass of Mohr's salt can be calculated by summing up the atomic masses of all the elements present in the compound. The atomic masses of ammonium (NH4+), iron(II) (Fe2+), sulfur (S), and oxygen (O) can be found in the periodic table.

3. Calculation of moles:
Using the mass of Mohr's salt and its molar mass, we can calculate the number of moles produced on dissociation using the formula mentioned earlier.

Number of moles = m / Molar mass

Example:
Let's take an example to illustrate the calculation. Suppose we have 10 grams of Mohr's salt.

1. Mass of Mohr's salt:
m = 10 grams

2. Molar mass of Mohr's salt:
The molar mass of (NH4)2Fe(SO4)2·6H2O can be calculated by summing up the atomic masses of all the elements present in the compound.

3. Calculation of moles:
Using the mass of Mohr's salt and its molar mass, we can calculate the number of moles produced on dissociation using the formula:

Number of moles = 10 grams / Molar mass

By performing the calculation, we can determine the number of moles produced on the dissociation of Mohr's salt for the given sample.

Summary:
- Mohr's salt dissociates into ammonium (NH4+), iron(II) (Fe2+), and sulfate (SO4^2-) ions.
- The number of moles produced on dissociation can be calculated using the formula: Number of moles = Mass / Molar mass.
