Determination Of Relative Molecule Mass Volatile Compounds

Abstract

Volatile compounds are compounds that easily evaporate into gas when the temperature increases. If these volatile compounds evaporate, the components will experience a decline in quality. The molecular weight of volatile compounds is measured based on measuring the density of the vaporized gas. is an organic compound that has a molecular weight of 50-200 Daltons, with a low molecular weight this compound can evaporate easily and diffuse in the gas phase and in biological systems. If these compounds evaporate, the quality of the aroma and taste of the components will decrease. The molecular weight of volatile compounds can be measured based on measuring the density of the vaporized gas. In 1807, Dalton's atomic theory was born, which states that matter consists of the smallest particles that cannot be divided, created or destroyed. Atoms of an element have the same properties (size, shape, mass) but are different from the properties of other elements. The relative molecular mass of a compound is the ratio of the average mass of 1 molecule of the compound to the mass of 1 atom12C. An ideal gas consists of a large number of particles evenly distributed throughout space, moves randomly in all directions, the distance between particles is much larger than the size of the particles, there are no interaction forces between particles, all collisions between particles or with walls are perfectly elastic and occur within a very short time, and Newton's laws of motion apply. In 1802, J Charles and J Gay-Lussac experimentally obtained the equation of state relationship ???????? = ???????? where this equation is called the ideal gas equation. to determine the relative molecular mass of a volatile compound by measuring the vapor density of the compound. The volatile compound used is chloroform (CHCL3) so that the density of chloroform is 3.692 ????????/????, and the relative molecular mass of chloroform is 111.282 gr/mol
