Vedclass · Answer

(A) To determine the number of significant figures,we follow these rules:$1$. For $23.023$: All non-zero digits and the zero between non-zero digits are significant. Thus,there are $5$ significant figures.$2$. For $0.0003$: Leading zeros are not significant. Only the digit $3$ is significant. Thus,there is $1$ significant figure.$3$. For $2.1 	imes 10^{-3}$: In scientific notation,the power of $10$ is not significant. The significant figures are determined by the coefficient $2.1$. Thus,there are $2$ significant figures.Therefore,the number of significant figures are $5, 1, 2$ respectively.

The number of significant figures in $23.023$,$0.0003$,and $2.1 \times 10^{-3}$ are respectively:
