Estimate one more place. Reading will be to the nearest 0.1 mL.
52.8 +/-0.1 mL estimated to be between 52.7 and 52.9 mL
How many significant digits does this measurement have?
3 sig figs (2 certain and one uncertain or estimated)
Significant figures: These are the numbers that tell us about the correct measurements of the values.
There are certain rules for the significant figures:
1) All non-zero numbers are significant.
2) Zeroes between two non-significant numbers are considered significant.
3) Leading zeroes i.e. zeroes that lie before decimal are considered non-significant.
4) Trailing zeroes i.e. zeroes that lie after the decimal are considered significant. for example, 32.00 has 4 significant figures.
