Elevation in boiling point of non volatile solute A and B are same. Mass percent of sol A is 2% and mass percent of sol B is 8%. What is the ratio of their molar mass?

What are the units of mass percent ?

Molecular mass of non-volatile solute can be determined by :

Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperaure and elevation in boiling point is marked. Ratio of DeltaT_(b)//K_(b) of 6% AB_(2) and 9% A_(2)B (AB_(2) and A_(2)B both are non-electrolytes) is 1 mol/kg in both cases. Hence, atomic masses of A and B are respectively.

Is the mass percent of a solution same as its strength ? Justify your answer.

What is the mass percent of carbon in carbon dioxide ?

Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperaure and elevation in boiling point is marked. Given that DeltaT_(b) is the elevation in boiling point of the solvent in a solution of molarity m then lim_(m rarr 0) ((Delta T_(b))/(m)) is equal to:
