Abnormal Molecular Masses
Abnormal Molecular Masses - The relation between colligative property and molecular mass of the solute is based on the following assumptions: i) The solution is dilute so that Raoult's law is obeyed. ii) The solute neither undergoes dissociation nor association in solu..

The law of mass action correlates the rate of a chemical reaction and the concentration of the reactants. C.M. Guldberg and P. Waage (1864-67) suggested this relationship. This law states that, at a constant temperature and pressure, the rate of a chemical reaction is directly propo..

D T b = k b m (1) If W B gms of the solute is dissolved in W A gms of the solvent then (where M B is the molar mass of the solute) From (1) and (2)..
D T b = k b m (1) If W B gms of the solute is dissolved in W A gms of the solvent then (where M B is the molar mass of the solute) From (1) and (2)..Step 7
The molecular mass (or molar mass) is obtained either from the experimental data or from the vapor density of the compound by using the relationship, Molecular mass = 2 x Vapor dens..
Conclusion
Solutions are homogeneous mixtures having great importance in our day to day life. In this chapter we have learnt the various types of solutions, the meaning of vapor pressure, Raoult's Law, Colligative Properties and Abnormal Molecular Masses..

Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
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 have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
Looking for More Help!
