6.13 x 1024 atoms of Na correspond to moles of Na. A) 10.17 moles
C) 4.24 moles
B) 2.52 moles
D) 3.45 moles
Show Calculation

6.13 x 10²⁴ atoms of Na = (6.13 * 10²⁴)/6.023 * 10²³ moles of Na = 10.17 moles

regular repeating structure

Explanation:

Crystalline solids have an organized structure involving repeating units of a particular structural pattern known as the unit cell. This well organized structural arrangement is maintained throughout the solid. Amorphous substances do not have this well organized structural units hence they are not as strong as crystalline solids and lack a definite pattern of arrangement of particles in the solid.
