<u>Answer:</u> The density of phosphorus is 
<u>Explanation:</u>
To calculate the density of phosphorus, we use the equation:

where,
= density
Z = number of atom in unit cell = 1 (CCP)
M = atomic mass of phosphorus = 31 g/mol
= Avogadro's number = 
a = edge length of unit cell =
(Conversion factor:
)
Putting values in above equation, we get:

Hence, the density of phosphorus is
