ABHISHEK JAIN AskiitiansExpert-IITD20 PointsDear Chanchal,since  chlorophyll contains 2.68% Mg therefore weight of Mg in 2g chlorophyll = 2×2.68/100 = .0536 g 
now Mole of Mg = weight/atomic weight                    = .0536/24       since 1 mole contains  6.023×10^23 particles        therefore number of atoms present in .0536/24 mole will be = (.0536/24) × 6.023×10^23                                                                           =1.34 × 10^23 atoms of Mg
