Ratio of `DeltaT_(b)//K_(b)` for `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 :

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.

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 respetively.

Ratio of DeltaT_(b)//K_(b) of 6% AB_(2) and 9% A_(2)BAB_(2) and A_(2)B both are non-electrolytes is 1 mol/kg in both cases. Hence atomic masses of A and B are respetively.

Ratio of (DeltaT_(b))/(K_(b)) of 10 g AB_(2) and 14g A_(2)B per 100 g of solvent in their respective, solution ( AB_(2) and A_(2)B both are non-electrolytes) is 1 mol/kg in both cases. Hence, atomic wt. of A and B are respectively.

Ratio of (/_\T_(b))/(K_(b)) of 10 g AB_(2) and 14 g A_(2)B per 100 g of solvent in their respective, solution ( AB_(2)and A_(2)B both are non-electrolytes ) is 1 mole/ kg in both cases. Hence, atomic wt. of A and B are respectively :

Ratio of (/_\T_(b))/(K_(b)) of 10 g AB_(2) and 14 g A_(2)B per 100 g of solvent in their respective, solution ( AB_(2)and A_(2)B both are non-electrolytes ) is 1 mole/ kg in both cases. Hence, atomic wt. of A and B are respectively :

Ratio of (triangle T_b)/K_b of 10 g AB_2 and 14 g A_2B per 100 g of solvent in their respective, solution ( AB_2 and A_2B both are non-electrolytes) is 1 mol/kg in both cases. Hence, atomic wt. of A and B are respectively

The element 'A' and 'B' combine together to give two compounds A_(2) B_(3) and AB_(2) . The weight of 0.2 mole of A_(2) B_(3) is 26 gm . The weight of 0.3 mole of AB_(2) is 24 g m . Then the atomic weight of A and B respectively
