Answer:
2.35mL
Explanation:
The amount of space a substance holds is its volume.
Density = mass (g) /volume (L)
Where;
mole = mass/molar mass
Since 1 mol of Cu contains 6.022 × 10^22 atoms.
There are 2 x 10^22/6.022 × 10^22 moles in 2 x 10^22 atoms of copper
2 x 10^22/6.022 × 10^22
2/6.022 × 10^(22-22)
0.332 × 10^0
0.332mol
Mole = mass/molar mass
0.332 = mass/63.5
mass = 63.5 × 0.332
mass = 21.08g
Density = mass/volume
Density of copper (Cu) is 8.96 g/cm³
8.96 = 21.08/v
V = 21.08/8.96
V = 2.35mL or cm³
