Some amount of dichloromethane (CH 2 C1 2 ) is added to 671.141 mL of chloroform (CHC1 3 ) to prepare 2.6x10 -3 M solution of CH 2 C1 2 (DCM).
The concentration of DCM is ______ ppm (by mass).
Given: Atomic mass : C = 12; H : 1; Cl = 35.5 density of CHC1 3 = 1.49gcm -3
Text Solution
Verified by ExpertsThe correct answer is:
GO FOR SOLUTION
(148)
Molarity = 
x = 0.148 g
cone. Fo DCM in ppm = 
= 148 ppm
