Options

A. 7
B. 4
C. 5
D. 2

Answer

To determine the number of significant figures in the number `0.0006032`, we can follow these steps:

### Step 1: Identify the Non-Zero Digits
The first step is to identify all the non-zero digits in the number. In `0.0006032`, the non-zero digits are `6`, `3`, and `2`.

### Step 2: Count the Non-Zero Digits
Now, we count the non-zero digits identified in Step 1.
- Non-zero digits: `6`, `3`, `2`
- Count: 3 non-zero digits

### Step 3: Identify the Zeros
Next, we need to look at the zeros in the number. The zeros in `0.0006032` are:
- Leading zeros: `0.0006` (these are not significant)
- The zero between `6` and `3`: This zero is significant because it is between two non-zero digits.

### Step 4: Count the Significant Zeros
From Step 3, we identified that the zero between `6` and `3` is significant. Therefore, we have:
- Significant zeros: 1 (the zero between `6` and `3`)

### Step 5: Total Count of Significant Figures
Now, we combine the counts from Step 2 and Step 4:
- Non-zero digits: 3
- Significant zeros: 1
- Total significant figures = 3 + 1 = 4

### Conclusion
Thus, the total number of significant figures in `0.0006032` is **4**.
