how many significant figures are in this number? 0.00521
Answer
Answer:
3
Explanation:
Step1: Identify non - zero digits
Non - zero digits are significant. In 0.00521, 5, 2, and 1 are non - zero.
Step2: Consider leading zeros
Leading zeros (zeros before non - zero digits) are not significant. Here, the three zeros before 5 are leading zeros and not counted. So the number of significant figures is 3.
