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 digits are in 4.00 and 7.0?
There are 3 significant digits in 4.00 and 2 significant digits in 7.0. Zeros between non-zero digits or at the end of a number after a decimal point are considered significant.

Why do you use significant digits when dealing with measurements?
Measurements need to be specific so we use significant digits.
How many significant digits are in 123.09?
Five. All nonzero digits are significant and zeros in between significant digits are significant.

What digits are considered significant in a measurement?
Non-zero digits are always significant. Thus, 569 has three significant digits, and 69.35 has four significant digits. Zeros are sometimes significant and sometimes aren't: # Zeroes placed before other digits are not significant; 0.0968 has three significant digits. # Zeroes placed between other digits are always significant; 70063 kg has five significant digits. # Zeroes placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. # Zeroes at the end of a number are significant only if they are behind a decimal point as in (c). Otherwise, it is impossible to tell if they are significant. For example, in the number 8200, it is not clear if the zeroes are significant or not. The number of significant digits in 8200 is at least two, but could be three or four. To avoid uncertainty, use scientific notation to place significant zeroes behind a decimal point: 8.200 * 103 has four significant digits 8.20 * 103 has three significant digits 8.2 * 103 has two significant digits
When is a number significant or not significant?
Any non-zero digit is significant. Example: 352.12 has 5 significant digits. A zero is significant if it appears between non-zero digits. Example: 504.2 has 4 significant digits. A zero is also significant when it appears after the decimal point, AFTER other digits. In this case, it was only added to indicate a significant digit. Example: 5.30 has 3 significant digits. A zero after other numbers may or may not be significant. Use scientific notation to unambiguously indicate the number of significant digits. Example: 4500 has 2 significant digits. It may have 3 or 4 significant digits, but to be safe, assume 2 significant digits. A zero is NOT significant if it comes after the decimal point, BEFORE any other digits. In this case, it is only used to put the digits in their proper place. Example: 0.0024 has 2 significant digits.
How many significant digits are in 7.0047?
