What is the atomic packing factor of hcp?
.74
What is packing fraction?
Are you referring to the packing factor in Crystallography? This is the proportion of volume taken up by atoms compared to the total volume. See Wikipedia entry for Atomic Packing Factor
What is the atomic packing factor for rock salt and how does it affect the crystal structure of the compound?
The atomic packing factor for rock salt is 0.74. This means that 74 of the space within the crystal structure is occupied by atoms. The high packing factor results in a closely packed arrangement of ions in a cubic structure, giving rock salt its characteristic high density and stability.
How many moles are in 746g of NaCl?
Atomic mass of NaCl = 23.0 + 35.5 = 58.5 Amount of NaCl = 746/58.5 = 12.8mol
Does packing factor affect on density?
Yes, packing factor does affect density. Packing factor refers to how closely atoms are packed in a material, which in turn influences the material's density. Materials with higher packing factors will have higher densities because the atoms are more closely packed together.
Show that the atomic packing factor for the Bcc crystal structure is 0.68?
In body-centred cubic structure,The no. of atoms per unit cell= 2Volume of 2 atoms (spherical)=2*(4/3)πr3We know the radius of atom in BCC isr = a√34Volume occupied by the atoms per unit cell(v) = 8πa√33 4v == 8πa33√3------- ---------3 4*4*4Volume occupied by the atoms per unit cell(v) =πa3√3----8Volume of the unit cell for a cubic system(V) = a3Atomic packing factor (APF) =(πa3√3/8)--------------a3√3(or) APF =π---------8APF = 0.68Therefore, we can say that 68% volume of the unit cell of BCC is occupied by atoms and remaining 32%volume is vacant.Thus the packing density is 68%.
How mny moles are in 23.34 of NaCl?
I'm going to assume that you mean 23.34g of NaCl. 1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 23.34g NaCl x (1mol NaCl/58.442g NaCl) = 0.3994mol NaCl
What is the mass of a mole of NaCl measured by?
The mass of one mole of NaCl is the sum of the atomic weights for sodium and chlorine in grams. The atomic weights are found on the periodic table.
Why it is formula is NaCl?
NaCl is sodium chloride. NaCl2 doesn't exist up today.
How many atoms in compound NaCl?
Atomic mass of sodium = 22.99 Atomic mass of chlorine = 35.45 Total mass = 58.44g 58.44g of NaCl contains 6.023 x 1023 atoms ... 18.035g of NaCl contains 18.035x6.023x1023/58.44 = 1.858x1023 atoms!
How does Atomic packing factor effect property of crystal?
The atomic packing factor (APF) influences the density, strength, and thermal properties of a crystal. A higher APF typically results in a denser crystal structure with stronger interatomic bonding, leading to higher density and increased mechanical strength. Additionally, a higher APF can also improve thermal conductivity due to the closer proximity of atoms in the crystal lattice.
What is packing factor in self compacting concrete?
Packing factor: In a simple way it is the ratio between the mass of tightly packed (compacted) to the mass of lossely packed.
