Chlorophyll extracted from the crushed green leaves was dissolved in water to make 2 L solution of Mg of concentration 48 ppm. The number of atoms of Mg in this solution is x 
10 20 atoms. The value of x is________. (Nearest Integer)(Given : Atomic mass of Mg is 24 g mol -1 , N A = 6.02x 10 23 mol -1 )
Text Solution
Verified by ExpertsThe correct answer is:
GO FOR SOLUTION
(24)
Number of Mg atoms = 4 x 10 -3 x 6.02 x 10 23
= 4 x 6.02 x 10 20
= 24.08 x 10 20
x = 24.08
