Find the number of water of crystallization in mol- ecule of butter of tin,

Answer

To find the number of water of crystallization in the molecule of butter of tin, we will follow these steps:

### Step 1: Identify the formula of butter of tin
The formula for butter of tin is given as SnCl4·5H2O. This indicates that it is a hydrated compound where SnCl4 is combined with water molecules.

### Step 2: Understand the concept of water of crystallization
Water of crystallization refers to the water molecules that are part of the crystalline structure of a compound. In the case of SnCl4·5H2O, the "5" indicates that there are 5 water molecules associated with each formula unit of SnCl4.

### Step 3: Count the number of water molecules
From the formula SnCl4·5H2O, we can see that there are 5 water molecules attached to the compound. Therefore, the number of water of crystallization in butter of tin is 5.

### Final Answer
The number of water of crystallization in the molecule of butter of tin is **5**.
