How many total atoms are present in `CoCl_(3). 6H_(2) O` ?

Options

A. 17
B. 22
C. 8
D. 18

Explanation

To find the total number of atoms in the compound \( CoCl_3 \cdot 6H_2O \), we will break down the components of the formula step by step.

### Step 1: Identify the components in the formula
The formula consists of:
- 1 Cobalt (Co)
- 3 Chlorine (Cl)
- 6 Water molecules (H2O)

### Step 2: Count the atoms in each component
1. **Cobalt (Co)**:
- There is **1** Co atom.

2. **Chlorine (Cl)**:
- There are **3** Cl atoms.

3. **Water (H2O)**:
- Each water molecule (H2O) contains:
- 2 Hydrogen (H) atoms
- 1 Oxygen (O) atom
- Since there are 6 water molecules, we calculate:
- Hydrogen atoms: \( 6 \times 2 = 12 \) H atoms
- Oxygen atoms: \( 6 \times 1 = 6 \) O atoms

### Step 3: Total the atoms
Now, we can add up all the atoms:
- Total Co atoms: **1**
- Total Cl atoms: **3**
- Total H atoms: **12**
- Total O atoms: **6**

Now, we sum these:
\[ 1 \, (Co) + 3 \, (Cl) + 12 \, (H) + 6 \, (O) = 22 \, \text{total atoms} \]

### Final Answer
The total number of atoms in \( CoCl_3 \cdot 6H_2O \) is **22**.
