B is correct because it doesn't depend on the movement just how the partials move at boiling point, ie it will expand but not gain motion
Answer:-
0.883 m
Explanation:-
Molality= Moles per Kg of solvent.
Molar mass of ethylene glycol= 62.07 g/ mol.
Number of moles of ethylene glycol= 82.2g / (62.07 g/mol)
= 1.324 moles
Density of water = 1 g/ml = (1/1000kg)/ (1/1000litre)
= 1 Kg / litre
Mass of 1.5 litre of water = 1.5 litre x 1 kg / litre
= 1.5 kg
Molality of ethylene glycol = 1.324 moles/1.5 kg
= 0.883 m
the components of the pure substance will not be able to be separated by physical means
