∙ 14y agoexample of unit price 250 cell phone minutes for 24.99 a month to figure out the unit price divide 24.99 bye 250 24.99/250 and then round up if 3rd decimal number is higher than 5 drop 3rd decimal number if lower than 5. Unit rate example 55 mph
The unit number after octillion is nonillion.
No.
unit
The unit is "per mole", or mol^-1.

why one of unit cell angles of hexagonal crystal is 120 digree
In a hexagonal close-packed (hcp) unit cell, there are a total of 6 atoms. This includes 3 atoms at the corners of the base layer, 1 atom at the center of the base layer, and 2 atoms on the top layer above the center atom.
The face-centered cubic (FCC) crystal structure has atoms arranged in a face-centered cubic unit cell with atoms at each corner of the cube and at the center of each face. Hexagonal close-packed (HCP) crystal structure has a hexagonal unit cell with atoms at each corner and one in the center of the top and bottom faces. In FCC, the stacking sequence is ABCABC, while in HCP, it is ABABAB.
A unit cell is the smallest repeating unit in a crystal lattice that when repeated in three dimensions creates the entire crystal structure. A single crystal is a solid in which the atoms are arranged in a repeating pattern without any boundaries or defects, representing a perfect crystal with continuous lattice structure.
To determine the number of atoms in a unit cell, you need to know the type of unit cell (simple cubic, body-centered cubic, or face-centered cubic) and the atom arrangement within the unit cell. For example, in a simple cubic unit cell, there is one atom at each corner. In a body-centered cubic unit cell, there are atoms at each corner and one in the center. In a face-centered cubic unit cell, there are atoms at each corner and one on each face. Counting these positions allows you to determine the total number of atoms in the unit cell.
In a face-centered cubic (FCC) structure, the lowest number of shared atoms in a unit cell is 4, and the highest number is 8. For unshared atoms, the lowest number is 0, and the highest is 4. In a simple cubic structure, the lowest number of shared atoms in a unit cell is 1, and the highest number is 8. For unshared atoms, the lowest number is 0, and the highest is 1.
There are two atoms per unit cell in the Body-Centered Cubic (BCC) crystal structure.
In a diamond unit cell, each carbon atom is located at the corners of the unit cell. Since there are eight corners in a unit cell, each shared by 8 adjacent unit cells, the contribution to the total number of carbon atoms is 1/8 of a carbon atom per unit cell. Therefore, there is 1 carbon atom per unit cell.
The repeating group of atoms in a crystal is called a unit cell. This unit cell is the smallest repeating structure that can be used to build up the entire crystal lattice.
The structural unit of the cell theory is the cell. The cell is the basic structural and functional unit of all living organisms.
