Answer

To determine the number of significant figures in the number 0.0035, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Non-Zero Digits**:

2. **Consider the Leading Zeros**:
- The zeros before the digits 3 and 5 (i.e., the 0s in 0.0035) are leading zeros. Leading zeros are not considered significant figures. Therefore, they do not contribute to the count of significant figures.

### Final Answer:
The number of significant figures in 0.0035 is **2**.
