Answer:
diameter is 2.36 nm
Explanation:
given data
atomic radius Ra = 0.148 nm
no of atoms = 106
radius r = 0.250 nm
to find out
diameter
solution
we know that diameter = 2 R ..........1
so we find R first
we apply equation here
volume of cluster = 106 × atom volume
put here volume
4/3 ×π×R³ = 106 × 4/3 ×π×r³
R³ = 106 × (0.250)³
R = 1.183
so from equation 1
diameter = 2 ( 1.183)
diameter = 2.36 nm
