<span> <span> </span></span>Volume = 4/3 * PI * r^3

1.59 x 10^24 copper atoms = 2.64 moles of copper
Atomic Mass of copper = 63.55
2.64 * 63.55 = 167.77 grams of copper
Volume of Copper = Mass / Density
Volume of Copper = 167.77 grams / 8.96
Volume of Copper = <span> <span> 18.72</span></span> cubic centimeters

r^3 = Volume / (4/3 * PI)
r^3 = 18.72 / 4.188
r^3 = <span> <span> <span> 4.47
radius = </span></span></span><span><span><span>1.647</span> centimeters

Why is glass brittle
WITCHER [35]
Glass doesn't contain planes of atoms that can slip past each other, so there is no way to relieve stress. It has many microscopic cracks that act as seeds for fracture. It’s molecular structure is composed of tetrahedral crystals so it ruptured easily under stress

How many ammonium ions and how many sulfate ions are present in an 0.260 mol sample of (nh4)2so4?
Anna11 [10]
The question requires that you assume complete ionization of the compound. This is:

(NH4)2 SO4 → 2 NH4 (+) + SO4 (2-)

Then, 1 mol of (NH4)2 SO4 produces 3 moles of ions: 2 moles of NH4 (+) and 1 mol of SO4 (2-)

=> 0.26 * 2 moles of NH4(+) = 0.52 moles of NH4 (+)

0.26 * 1 mol of SO4 (2-) = 0.26 moles of SO4 (2-).

Answer: 0.52 moles of ammonium ions and 0.26 moles of sulfate.ions.
