Question

The incorrect rule regarding the determination of significant figures is:

• A. Zeros preceding to first non-zero digit are not significant.
• B. Zeros between two non-zero digits are not significant.
• C. Zeros at the right end of the number are significant if they are on the right side of decimal point.
• D. All non-zero digits are significant.

Hint:

Trailing zeros are only significant if a decimal point is present.
- Leading zeros are never significant; they only serve as placeholders.

Answer 1

The Correct Option is B

The rules for significant figures are:
1. Non-zero digits are always significant.
2. Leading zeros (zeros before the first non-zero digit) are NOT significant.
3. Trailing zeros (zeros at the right end) are significant only if there is a decimal point.
4. Zeros between two non-zero digits are always significant.
Option (2) is incorrect because zeros between two non-zero digits ARE significant.
Thus, the correct answer is \(\boxed{\text{Zeros between two non-zero digits are not significant.}}\).
