Question

how many significant figures does the value 0.0006700 have?
2
7
4
8

Explanation:

Step1: Recall significant - figure rules

Non - zero digits are always significant. Leading zeros (zeros before non - zero digits) are not significant. Trailing zeros (zeros after non - zero digits) are significant if there is a decimal point.

Step2: Analyze the number 0.0006700

The non - zero digits 6 and 7 are significant. The leading zeros (the four zeros before 6) are not significant. The two trailing zeros after 7 are significant because of the decimal point. So in total, there are 4 significant figures.
