moles of sodium is equal to 46 divided by mass number of sodium that is 2
number of particles is equal to Avogadro number into moles that is 2 into 6. 022 into 10 to the power 23

Hii There!!!
We know that atomic mass of Na atom = 23u
∵Number of particles=Number of Moles x N
✔Here we have to calculate number of particles and value of 'N' i.e, avogadro's no. = 6.022× 10²³
On substituting values in the above formula we get ;
=> (46 / 23) x 6.023 x 10²³
=> 2x 6.023 x 10²³
=> 12.046 x 10 ²³Na particles
∴46 g of Na contains 12.044 x 10 ²³
