Can I solve it like this ?
no. of moles of element = no. of particles / 6.22 * 10^23 particles


No. of moles of a element : mass of element in g / molar mass of element in g/mol

= 4.86 / 28 = 0.1736 * 6.22 * 10^23 
= 1.079792e23

how did you get 0.1736?

Yes, you can do it like that, but it would be this way:

  4.86 / 28 = X /6.22 * 10^23
