Given that,

Volume, d = 2 mL

Mass, m = 18 grams

We have to find the density. Density of an object is equal to mass per unit volume. It can be given by:

$d=\dfrac{m}{V}\\\\d=\dfrac{18\ g}{2\ cm^2}\\\\d=9\ g/cm^3$

So, the density is 9 g/cm³.

Iron has a mass of 7.87 g per cubic centimeter of volume, and the mass of an iron atom is 9.27 × 10-26 kg. If you simplify and t

Talja [164]

(a) what is the average volume (in cubic meters) required for each iron atom
For this case, the density of Iron would be 7.87g/cm³

V = 9.27 x 10^-26 kg / 7.87g/cm³ ( 1 kg / 1000 g)
V = 1.18 x 10-23 cm³

(b) what is the distance (in meters) between the centers of adjacent atoms?
We assume the atoms as cube, so we use the volume of the cube to calculate the distance of the atoms.

V = 1.18 x 10-23 cm³ = s³
s = 2.28 x 10^-8 cm
