The number of significant figures in 0.098000 is:
Correct answer: C. 5
- A. 4
- B. 2
- C. 5
- D. 6
Explanation
As per the rule for significance: "Every zero which has a value has no significance and every zero which has no value has significance"In 0.098000The zero that is right after the decimal 0.0 has a value so its significance is zero. 9 and 8 are numbers so they have significanceThe last 3 zeros have no value so they will have significance. So, in 0.098000, 0.098000 these 5 numbers are significant. Hence, the number of significant figures is 5.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
