The measurement of 0.0450 grams has **3 significant figures**.
Here's how we determine that:
- The leading zeros (0.04) are not significant.
- The digits 4 and 5 are significant.
- The trailing zero (0) after the 5 is significant because it indicates precision in the measurement.
Therefore, the significant digits are 4, 5, and the trailing zero, giving a total of 3 significant figures.
