Answer:
3.68 grams.
Explanation:
First we convert 9.5 g of NaCl into moles of NaCl, using its molar mass:
9.5 g ÷ 58.44 g/mol = 0.16 mol NaCl
In 0.16 moles of NaCl there are 0.16 moles of sodium as well.
We now convert 0.16 moles of sodium into grams, using sodium's molar mass:
0.16 mol * 23 g/mol = 3.68 g
