Question

9/22 how many significant figures: 0.010 l 3 1 4 2

Explanation:

Step1: Recall sig fig rules

Leading zeros (before non - zero digits) are not significant. Non - zero digits are significant. Trailing zeros after a decimal point are significant.
For the number \(0.010\) L: The leading zeros (the two zeros before 1) are not significant. The digit 1 is significant. The trailing zero after the decimal (after 1) is significant.

Step2: Count significant figures

So we have two significant figures (1 and the trailing 0).
