Vedclass · Answer

(B) The number of significant figures in a scientific notation $a 	imes 10^n$ is determined by the number of significant digits in the coefficient $a$.In the given expression $0.310 	imes 10^3$,the coefficient is $0.310$.According to the rules for significant figures,leading zeros are not significant,but trailing zeros after a decimal point are significant.Therefore,the digits $3$,$1$,and $0$ are significant.Thus,the number of significant figures is $3$.
