Explanation:
Hi! Here are the rules in identifying significant figures:
- all non-zero digits are significant
- all digits of a measured quantity including the uncertain one
- for figures including zero:
- zeros between non-zero digits are significant
(ex: 1005 kg#-># 4 significant number; 1.03 cm#-># 3 significant numbers) - zeros at the beginning of a number are never significant
(ex: 0.02 g#-># 1 significant number; 0.0026 g#-># 2 significant numbers) - zeros at the end of a number are significant if the number contains a decimal point
(ex: 0.0200 g#-># 3 significant figures; 3.0 cm#-># 2 significant numbers)
- zeros between non-zero digits are significant
