Answer:
4 sig figs.
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).
We look at 0.001022.
We know that 0.00 are not sig figs and are placeholders.
We know that 1022 are significant digits and figures, and we have 4 of them.
Therefore, we have 4 sig figs.
