a = edge length = 560.5 pm.
4*radius = a*31/2
Convert a to cm here, I think it is easier here than later.
Then volume = a^3 in cc.
density = mass/volume so we need to calculate mass.
mass of unit cell = #atoms per unit cell*molar mass Rb/6.02E23 = ?
Rubidium crystalizes in the body centred cubic structure with an edge length of 560.5 pm..
a. calculate the radius (in pm) to 4 sig figures.
b. calculate the density to 4 sig.fgures.
thnks guys..

can u please explain to me where did u get the 3 to find radius?..
thank you..
thank you..
and also how to get the # of atoms per unit cell...
