The number of significant figures in 0.00200 is
Correct answer: B. three
- A. two
- B. three
- C. five
- D. one
Explanation
The number of significant figures in a given number is determined by the non-zero digits, any zeros between them, and any zeros to the right of the decimal point and after a non-zero digit. In the case of 0.00200:The leading zeros before the non-zero digit (2) are not considered significant.The non-zero digit (2) is always significant.The zeros between the non-zero digit and the decimal point are not significant.The trailing zeros to the right of the decimal point and after a non-zero digit are considered significant.Therefore, in 0.00200, there are three significant figures. The correct answer is three.
