The osmotic pressure of a 0.010 M MgSO4 solution at 500 K is 0.82 atm. Calculate , the van’t Hoff factor, for this MgSO4 solution.
Benzoic acid dissolved in benzene will show a molecular weight of
In benzene, benzoic acid exist as dimer. So the molecular weight of benzoic acid gets doubled.
(C6H5COOH)2=2×122=244 units .
Molar mass that is either lower or higher than expected or normal molar mass is called as
0.01 M solution of common salt (NaCl) and (CH3COOH ) is taken. If their osmotic pressures are p1and p2 resp., what will be the correct statement correlating their osmotic pressures?
If α is the degree of dissociation of Na2SO4, the vant Hoff’s factor (i) used for calculating the molecular mass is
Lowering of vapour pressure is highest for
Increasing the temperature of solution of a weak electrolyte will cause
What is the freezing point of 0.1 m glucose solution in water? For water Kf is 1.86 K kg/mol?
van’t Hoff factor is denoted by letter
The ratio of osmotic pressure of a 1:1 electrolyte AB to that of a non electrolyte solute of same concentration is
