Answer:
0.00900 has 3 significant figures, "9", "0", and "0". The significant figures are shown in bold. This is true because:
-All non-zero digits are significant (the nine)
-All zeroes trailing the first non-zero digits are NOT significant (the first three zeroes)
-If a number has a decimal point, all zeroes AFTER the last non-zero digit are significant (the last two zeroes). Therefore, it has 3 significant digits.

Significant Figures
à Non-zero numbers are always significant figures.
à Zeros are tricky:
- If zeros appear before a non-zero (called leading zeros), they are NEVER significant (ex: 0.025)
- If zeros fall between non-zero numbers, they are ALWAYS significant (ex: 205)
- If zeros come at the end of the number, they WILL be significant only IF there is a decimal present (ex: 250.0)
à Exact numbers (or counting numbers) have infinite significant figures. For example, if we count 3 pencils, we know there are exactly 3 pencils. Or, when we say 1 inch = 2.54 cm, we know this is for exactly 1 inch.

How many significant figures in 10.001?
There are five significant figures in 10001. The 1s are significant because they are non-zero digits. The zeros are significant because they are "captured" zeros, meaning they are between non-zero digits.
How do you round numbers to 3 significant figures?
There are three rules that are used when rounding to a desired number of significant digits (figures): 1. All digits that are not zero, are significant 2. In a number that does not have a decimal point, all zeros between two non-zero digits are significant digits 3. In a number that has a decimal point, all zeros after the leftmost non-zero digit are significant Examples: 12345 rounded to 3 significant digits: 12300, or 1.23 x 104 12.345 rounded to 3 significant digits: 12.3, or 1.23 x 101 0.012345 rounded to 3 significant digits: 0.0123, or 1.23 x 10-2 0.012045 rounded to 3 significant digits: 0.0120, or 1.20 x 10-2 In the last example the zero after 2 is significant. That is the reason for keeping it in the result when rewriting it in powers of 10 notation.
Why do you use significant digits when dealing with measurements?
