Explanation:

Significant Figures Rules:

1. Anything that isn't a zero is a sig fig

2. If a decimal point comes after the ones digit, everything before the decimal is counted as sig fig (i.e 2000. would be 4 sig figs).

3. If we are dealing with small decimals, the zero before and after the decimal (i.e 0.002) is a placeholder and is not counted as sig figs.

4. Any zeros between 2 significant digits is considered in sig figs (i.e 2002 would be 4 sig figs)

5. Any zeros after a significant digit in a decimal (i.e 0.020) is considered a sig fig

0.0102 would be 3 sig figs. Rounding to the thousandths place of 0.010 would be 2 sig figs.
