Find molarity, molality, percentage composition, boiling and freezing point of a solution.

Data

Element Atomic wt Electronegativity

H 1.01 2.1
B 10.81 2.0
C 12.01 2.5
N 14.00 3.0
O 16.00 3.5
F 19.00 4.0

Molarity = moles /Litre

Molality = moles/ kg of solvent = C_m

%m/m = ( mass of component / mass of sample) x 100

?T_b = K_b.C_m K_b water = 0.512 BP pure water = 100 ^oC
?T_f = K_f. C_m K_fwater = 1.858 FP pure water = 0.00 ^oC
