Vapour pressure of water,P1=23.8 m of hg The weight of water=850 g The weight of Urea=50 g The molecular weight of water(H_2O)=1×2+16=18 g mol−1 molecular weight of urea (NH2CONH2)=2N+4H+C+O=2×14+4×1+12+16=60 g mol−1 Use formula number of moles=molar massmass number of moles of water n1=18850=47.22 number of moles of urea n2=6050=0.83 Now, we have to calculate the vapour pressure of water in the solution. we take vapour pressure as P1. Use the formula of Raoult's law P10P10−P1=n1+n2n2 plug the values we get 23.823.8−P1=47.22+0.830.83 23.823.8−P1=0.0173 23.8−P1=23.8×0.0173 P1=23.4 m Hg Vapour Pressure of water in the given solution=23.4 mm of Hg Relative lowering=0.0173

The stability of coordination compounds in solution means the degree of association between the metal ion and the ligands involved in the state of equilibrium. Quantitatively, the stability is expressed by the equilibrium constant for the association. Factors affecting the stability of a complex ion: (a) The nature of the central metal atom (1) Charge on the central metal ion (2) Size of metal ion (3) Electronegativity or charge distribution of metal ion (4) Chelate effect (5) Macrocylic effect (b) The nature of the ligand (1) Basic strength (2) Size and charge of ligands

1Thank You

Royal Thakur 3 years, 3 months ago

Haloalkane are dissolve in organic
solvent because the bond formed between Haloalkane
and organic solvent has same strength as the being broken

1Thank You

Anjan Karthi 3 years, 3 months ago

Nature of bonds in haloalkanes and organic solvents are the same ie, dipole-dipole interactions. Thus, consequently lesser energy would be required to break the existing bonds between solvents and to form new bonds between solvents and solute. So, easy dissolution. Hope this helps !!!!!

Explain why limiting molar conductance of weak alelctrolytes cannot be determined directly at infinite dilution . How it can be obtained ?

Posted by Chuesha Marak 3 years, 3 months ago

Harsh Mishra 3 years, 2 months ago

It can be obtained only : For example you need to find the limiting molar conductance of CH3COOH So first you need to find the Limiting molar conductance of Strong electrolyte having CH3COO in it i.e CH3COONa-- CH3COO- and Na+ Now find Limiting molar conductance of NaCl- Na+ and Cl- Now find Limiting molar conductance of HCl- H+ and Cl- And add all the reactions You will get LMC of CH3COOH
