This video shows you how to calculate the theoretical and percent yield in chemistry. The theoretical yield is the maximum amount of product that can be produced in a reaction. The percent yield is equal to the actual yield divided by the theoretical yield times 100%.

In this video i have explain Crystalline solids exhibit a regular and repeating pattern of constituent particles. The diagrammatic representation of the three dimensional arrangement of constituent particles in a crystal, in which each particle is depicted as a point in space is known as crystal lattice. The crystal lattice of a solid can be described in terms of its unit cell. A crystal lattice is made up of a very large number of unit cells where every lattice point is occupied by one constituent particle.The unit cell can be seen as a three dimension structure containing one or more atoms. We can determine the volume of this unit cell with the knowledge of the dimensions of the unit cell. For example: if we have a unit cell of edge “a”, the volume of the unit cell can be given as “a3”. Density of a unit cell is given as the ratio of mass and volume of unit cell. The mass of a unit cell is equal to the product of number of atoms in a unit cell and the mass of each atom in unit cell. -~-~~-~~~-~~-~- Please watch: "CLASSIFICATION OF ELEMENT|CLASS 12|PART 1|EFFECTIVE NUCLEAR CHARGE|SCREENING EFFECT/SHIELDING EFFECT" https://www.youtube.com/watch?v=wJbSvAx8zOE -~-~~-~~~-~~-~-

Body centered cubic (BCC) and face centered cubic (FCC) unit cells are introduced using models. These two unit cells are then broken down into how many atoms are present for each, which atoms are in contact with one another and how to relate the length of the unit cell with the radius of the atoms composing them. A density problem is solved where the density of aluminum packed in a FCC arrangement is used to find the radius of an aluminum atom. The atoms at the corner of a unit cell have only 1/8th count towards each unit cell, the atoms on a side count 1/4th, the atoms on a face count 1/2 and any atoms completely internal to the unit cell are not shared and thus count the full atom towards the unit cell.
