Vedclass · Answer

(B) Density $\rho$ is given by the formula $\rho = \frac{m}{V}$.Given mass $m = 4.237 \ g$ (which has $4$ significant figures).Given volume $V = 2.5 \ cm^3$ (which has $2$ significant figures).Calculating the density: $\rho = \frac{4.237}{2.5} = 1.6948 \ g \ cm^{-3}$.According to the rules of significant figures,the result of division should have the same number of significant figures as the measurement with the fewest significant figures.Since $2.5$ has $2$ significant figures,the final answer must be rounded to $2$ significant figures.Rounding $1.6948$ to $2$ significant figures gives $1.7 \ g \ cm^{-3}$.

The mass and volume of a body are $4.237 \ g$ and $2.5 \ cm^3$,respectively. The density of the material of the body in correct significant figures is $:-$ (in $g \ cm^{-3}$)
