The number of atoms in 4.4 moles of Fe are?

Options

A. 34.4×`10^23`
B. 26.4×`10^23`
C. 4.4×`10^23`
D. 38.5×`10^23`

Explanation

To find the number of atoms in 4.4 moles of iron (Fe), we can follow these steps:

### Step-by-Step Solution:

1. **Understand Avogadro's Number**:
- Avogadro's number states that one mole of any substance contains approximately \(6.02 \times 10^{23}\) entities (atoms, molecules, etc.).

2. **Identify the Given Information**:
- We are given that we have 4.4 moles of iron (Fe).

3. **Calculate the Number of Atoms**:
- To find the total number of atoms in 4.4 moles of iron, we multiply the number of moles by Avogadro's number:
\[ \text{Number of atoms} = \text{Number of moles} \times \text{Avogadro's number} \]
\[ \text{Number of atoms} = 4.4 \, \text{moles} \times 6.02 \times 10^{23} \, \text{atoms/mole} \]

4. **Perform the Calculation**:
- Now, calculate:
\[ \text{Number of atoms} = 4.4 \times 6.02 \times 10^{23} \]
- First, multiply \(4.4\) by \(6.02\):
\[ 4.4 \times 6.02 = 26.488 \]
- Therefore, the total number of atoms is:
\[ 26.488 \times 10^{23} \, \text{atoms} \]

5. **Final Answer**:
- We can round this to \(26.4 \times 10^{23}\) atoms.

### Conclusion:
The number of atoms in 4.4 moles of iron is \(26.4 \times 10^{23}\) atoms.
