Tungsten has a density of 19.35 g `cm^(-3)` and the length of the side of the unit cell is 316 pm. The unit cell is a body centred unit cell. How many atoms does 50 grams of the element contain?

Text Solution

Verified by Experts

For bcc, Z=2, a=316 pm = `316xx10^(-10)` cm
d=19.35 g/cc w=50
Number of atoms =`(Zxxw)/(a^3xxd)=(2xx50)/((316xx10^(-10))^3xx19.35)`
`=1.64xx10^23` atoms
