Determination of Molecular Mass
The molecular mass of a compound is essential to determine its molecular formula. Molecular mass of an organic compound is determined by a number of methods..
Determination of Molecular Mass - Continued
Silver salt method is used for determining the molecular masses of carboxylic acids. This method is based on the fact that they form insoluble silver salts, which upon heating decompose to leave a residue of metallic silve..
Determination of Molecular Mass from Osmotic Pressure
In order to determine the molecular mass of unknown non volatile compound, a known mass (say w g) of the compound is dissolved to prepare a known volume (say v liters) of solution. The osmotic pressure of the solution is determined and the molar ..

Process
A liquid (water), having boiling point about 20 to 30C higher than that of the given liquid (whose molecular mass is to be determined) is poured into the outer jacket so as to fill its bulb up to one-third its capacity. Cleaned and dried Victor Meyer..
Percentage Composition of a Compound
The mass percentage of each constituent element present in any compound is called its percentage composition. This may be obtained from the molecular formula of the compound by using the relationship:..
Introduction
Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to characterize them, it is imp..

Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
I could not get time to help my daughter with her homework so I looked on net about online tutoring, we tried tutorvista for a week, my daughter liked it, so, now I got her join it.
