atomic mass of sodium is 23
no. of mole= given mass /atomic mass
n=9.2/23
n=0.4
no. of atom = 0.4*6.022*10^23
no. of mole= given mass /atomic mass
n=9.2/23
n=0.4

Answer:
No. of atoms = 2.409*10^23 atoms
Explanation:
We know that,
n=W/M and n= N0/NA
=> W/M = N0/NA
=>9.2/23=N0/6.023*10^23
=>N0=0.4*6.023*10^23
=N0=2.409*10^23-ans.
