The molality of a 10% (v/v) solution of di-bromine solution in CCl 4 (carbon tetrachloride) is V. x = ________x 10 -2 M (Nearest integer)
[Given : molar mass of Br 2 = 160 g mol -1 atomic mass of C = 12 g mol -1 atomic mass of Cl = 35.5 g mol -1 density of dibromme = 3.2 g cm -3 density of CC1 4 = 1.6 gcm -3 ]
Text Solution
Verified by ExpertsThe correct answer is:
GO FOR SOLUTION
(139)
(10 ml solute in 90 ml solvent mass of solute = 10 x 3.2 = 32g mass of solvent = 90 x 1.6g
m = 138.8 x10 -2 = 139
