An element has a bcc structure with a celledge of `288` pm. The density of the element is `7.2 g cm^(-3)`. How many atins are present in `208 g` of the element?
Text Solution
Verified by Experts
Volume of the unit cell =`(288"pm")^(3)` `=(288xx10^(-12)m)^(3)=(288xx10^(-10)cm)^(3)` `=2.39xx10^(-23)=cm^(3)`
