Explanation Mass is the measuring quantity and it describes the amount of matter in an object and it is usually measured in grams (g) or kilograms (kg)… Different atoms and molecules have different masses and so, depend on the number of atom and molecule mass of the substances will be changed. Molecular mass is the mass obtained by the addition of relative atomic mass of elements present in the corresponding compound. Mass of the substance in gram = Molecular mass of the substance Avagadro number Avogadro number is 6.022 × 10 23 . Molecular mass is the mass obtained by the addition of relative atomic mass of elements present in the corresponding compound. And it is expressed in gram/mol. Molecular mass of water molecule = mass of hydrogen atom + mass of oxygen atom = (2×1 .01 )+ (1×16 ) = 18

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…
