given mass = 11.5
molar mass of Na =23
no. of moles of Na = 11.5 / 23
= 1/2
no. of atoms = no. of moles × avagadro no.
= 1/2 × 6.022 × 10^23
= 3.022 × 10 ^23 atoms
molar mass of Na =23
no. of moles of Na = 11.5 / 23
= 1/2
no. of atoms = no. of moles × avagadro no.
= 1/2 × 6.022 × 10^23
= 3.022 × 10 ^23 atoms

Answer:
Answer will be 3.011 ×10^23
Explanation:
Atomic mass of Na =23u
given =11.5
no. of moles =11.5 /23=1/2
no.of atoms =6.022×10^23 ×1/2
=3.011×10^23
