Give the order of the following :
Avogadro constant (`6.02xx10^(23)"mol"^(-1)`)

Answer

To find the order of the Avogadro constant, which is given as \(6.02 \times 10^{23} \, \text{mol}^{-1}\), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number in scientific notation**: The Avogadro constant is expressed as \(6.02 \times 10^{23}\). Here, \(a = 6.02\) and \(b = 23\).

2. **Determine the value of \(a\)**: In this case, \(a = 6.02\), which is greater than 5.

3. **Apply the rule for determining order**:
- If \(a < 5\), the order of magnitude is \(b\).
- If \(a \geq 5\), the order of magnitude is \(b + 1\).
Since \(6.02\) is greater than \(5\), we will use the second rule.

4. **Calculate the order of magnitude**:
\[ \text{Order} = b + 1 = 23 + 1 = 24 \]

5. **Final Result**: The order of the Avogadro constant is \(24\).
