Answer:
Since NaCl has a molar mass of 23.0 g/mol + 35.5 g/mol = 58.5 g/mol, we see that we have:
Moles NaCl = (11.7 g)/(58.5 g/mol) = 0.20 mol.
This corresponds to 0.20*23.0 = 4.60g of sodium........
Hope this helps you....

Answer:
Na mass =23
Cl mass =35.5
NaCl mass =58.5
58.5 g of NaCl consists of 23g of Na
11.7 g of NaCl consists of x grams
x=23×11.7/58.5
x=4.6g
