Grams of sodium 9.5g in NaCl <br>​
Kitty [74]

Answer:

3.68 grams.

Explanation:

First we <u>convert 9.5 g of NaCl into moles of NaCl</u>, using its<em> molar mass</em>:

9.5 g ÷ 58.44 g/mol = 0.16 mol NaCl

In<em> 0.16 moles of NaCl there are 0.16 moles of sodium </em>as well.

We now <u>convert 0.16 moles of sodium into grams</u>, using <em>sodium's molar mass</em>:

0.16 mol * 23 g/mol = 3.68 g
