Answer:
3 significant figures
Explanation:
- Zeros that come before any non-zero digits are never significant.
- Zeros that are in between any non-zero digits are always significant.
- Zeros that come after any non-zero digit are ONLY significant if a decimal point is present somewhere in the number. (In this case there is a decimal point.)
I underlined the significant figures in this number:
0 . 0 0 1 3 0
