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