**Equivalent Weight of SnCl2**

To determine the equivalent weight of SnCl2 in the given reaction SnCl2 + Cl2 -> SnCl4, we need to understand the concept of equivalent weight.

**What is Equivalent Weight?**
The equivalent weight of a substance is defined as the amount of the substance that supplies or reacts with one mole of hydrogen ions (H+) or one mole of electrons (e-) in a chemical reaction.

**Calculating Equivalent Weight of SnCl2**

To calculate the equivalent weight of SnCl2, we need to consider the stoichiometry of the reaction and the number of equivalents of SnCl2 involved.

In the given reaction, the stoichiometric coefficient of SnCl2 is 1. This means that one mole of SnCl2 reacts with one mole of Cl2 to produce one mole of SnCl4.

**Step 1: Calculate the Molar Mass of SnCl2**
The molar mass of SnCl2 can be calculated by adding the atomic masses of tin (Sn) and two chlorine (Cl) atoms.
Molar mass of SnCl2 = Atomic mass of Sn + 2 × Atomic mass of Cl

The atomic mass of Sn is 118.71 g/mol, and the atomic mass of Cl is 35.45 g/mol.
Molar mass of SnCl2 = 118.71 g/mol + 2 × 35.45 g/mol = 189.61 g/mol

**Step 2: Calculate the Number of Moles of SnCl2**
To determine the number of moles of SnCl2, we divide the given mass of SnCl2 by its molar mass.
Number of moles of SnCl2 = Mass of SnCl2 / Molar mass of SnCl2

**Step 3: Calculate the Number of Equivalents of SnCl2**
The number of equivalents of SnCl2 is equal to the number of moles of SnCl2 because the reaction involves one mole of SnCl2.
Number of equivalents of SnCl2 = Number of moles of SnCl2

**Step 4: Calculate the Equivalent Weight of SnCl2**
The equivalent weight of SnCl2 is calculated by dividing the molar mass of SnCl2 by the number of equivalents of SnCl2.
Equivalent weight of SnCl2 = Molar mass of SnCl2 / Number of equivalents of SnCl2

**Step 5: Substitute the Values**
Substituting the calculated values into the equation:
Equivalent weight of SnCl2 = 189.61 g/mol / Number of moles of SnCl2

**Step 6: Final Calculation**
The final calculation of the equivalent weight of SnCl2 depends on the given mass or number of moles of SnCl2.
