no of moles of Na = mass of Sodium/molar mass
1) frist we have to divide mass of Na w.r.t molar mass of Na
#) molar mass of Na =23 gm/mol
#) no of moles of Na =46/23
=2mol
2) than we easily get the no of moless.
no of atoms in Na =2 * avocadro no= 2 * 6.03 *10^23 =12.06 *10^23 atom
3) than we have to multiply the no of moless wd avocadro no.

Number of particles = No: of moles × Avogadro no :
Given mass of Na (Sodium) = 46 g
Molar mass of Na = 23 g
No: of moles = Given mass ÷ Molar mass
= 46 ÷ 23
= 2 moles
∴ Number of particles = 2 moles × 6.022 × 10²³
= 12.044 × 10²³
