Vedclass · Answer

(B) Step $1$: The mass of one unit cell is given by the product of its volume $(V)$ and its density $(d)$.Mass of one unit cell = $V 	imes d = 6.65 	imes 10^{-23} 	ext{ g}$.Step $2$: The number of unit cells in a given mass of metal is calculated by dividing the total mass of the metal by the mass of one unit cell.Number of unit cells = $\frac{	ext{Total mass}}{	ext{Mass of one unit cell}}$.Step $3$: Substitute the given values:Number of unit cells = $\frac{0.5 	ext{ g}}{6.65 	imes 10^{-23} 	ext{ g}} = 0.07518 	imes 10^{23} = 7.518 	imes 10^{21}$.Thus, the correct option is $B$.

Calculate the number of unit cells in $0.5 \text{ g}$ of a metal if the product of the volume and density of the unit cell is $6.65 \times 10^{-23} \text{ g}$.
