Chlorophyll extracted from the crushed green leaves was dissolved in water to make \( 2 \, \mathrm{L} \) solution of Mg of concentration \( 48 \, \mathrm{ppm} \). The number of atoms of Mg in this solution is \( x \times 10^{20} \) atoms. The value of \( x \) is _________. (Nearest Integer)
(Given : Atomic mass of Mg is \( 24 \, \mathrm{g \, mol^{-1}} \); \( N_A = 6.02 \times 10^{23} \, \mathrm{mol^{-1}} \) )
