Question

how many significant figures are in the number 0.0107
possible points: 1

• three

○ four
○ one
○ two

Explanation:

Step1: Recall significant figure rules

Leading zeros (zeros before the first non - zero digit) are not significant. Non - zero digits are significant. Zeros between non - zero digits are significant.
For the number \(0.0107\):

• The leading zeros (the two zeros before \(1\)) are not significant.
• The digit \(1\) is non - zero, so it is significant.
• The zero between \(1\) and \(7\) is significant (because it is between two non - zero digits).
• The digit \(7\) is non - zero, so it is significant.

Step2: Count the significant figures

Counting the significant figures: \(1\), \(0\) (between \(1\) and \(7\)), and \(7\). So there are 3 significant figures.

Answer:

The correct option is: A. three (assuming the option with "three" is labeled as A, if the original options have labels like A, B, C, D, we need to use the correct label. Since in the given problem, the option "three" is selected, and if we consider the options as: A. three, B. four, C. one, D. two, then the answer is A. three)
