wt of 1 mole NaCl - 58.5
wt of Na ion - 23
wt of Cl ion - 35.5
for mass% =(wt. of ion /wt of mol. nacl )× 100
so ans
for Na %mass is 39.3%
for Cl %mass is 60.7%

Begin by finding the mass of the NaCl molecule.
Na = 22.99
Cl = 35.45
NaCl = 58.44
Now you need to divide the mass of sodium by the mass of the molecule in order to determine the percent of sodium.
22.99/58.44 = 0.3933
Na = 39.33% of NaCl
This means that 100% - Na = Cl
Cl = 60.67%
