Concept explainers
(a)
Interpretation:
The number of significant figures in "160." needs to be determined.
Concept Introduction:
The rules to determine the significant figures in a number are as follows:
- Digits which are non-zero are always significant.
- Between two significant digits, if there is any non-zero digit present then it is significant.
- The trailing zeroes or final zero within the decimal portion are only significant.
Also, if there is any zero at the end of the number followed by a decimal, it is considered as a trailing zero hence, it is a significant zero.
(b)
Interpretation:
The number of significant figures in 160.0 needs to be determined.
Concept Introduction:
The rules to determine the significant figures in a number are as follows:

(c)
Interpretation:
The number of significant figures in 0.00016 needs to be determined.
Concept Introduction:
