Question
Sodium metal (atomic weight 22.99 g/mol) adopts a
body-centered cubic structure with a density of 0.97 g/cm3.
(a) Use this informat ion and Avogadro’s number
1NA = 6.022 x1023/mol2 to estimate the atomic radius of
sodium. (b) If sodium didn’t react so vigorously, it could
float on water. Use the answer from part (a) to estimate
the density of Na if its structure were that of a cubic closepacked
metal. Would it still float on water?
