number of moles \[n=\frac{ w }{ m }\] but here you have been given atoms and one mole =6.022 *10^23 atoms there fore number of moles are \[n=\frac{ 4.8*10^{25} }{ 6.022*10^{23} }=79.707 \]

one mole has 6.02*10^23 atoms 1 atom is there in 1/6.02 *10^23 moles therefore 4.8 *10^25 will be in 4.8*10^25/6.02*10^25 and answer is B
