Question

How many significant figures does 0.00130 have

Answer 1

3 significant figures

Step-by-step 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
