Na has a mass of 23 grams and Cl has a mass of 35.5 grams. You can produce $62.62$ grams of table salt.

#### Explanation:

In order to produce 1 mol of NaCl, you need 23 grams of Na and 35.5 grams of Cl. NaCl has a molecular mass of 58.5 grams.

$N a + C l \to N a C l$

Now try these: Your Na is in excess. But your Cl is not.

If 35.5 grams of Cl react with 23 grams of Na to form 1 mole ($58.5$ grams) of table salt, 38 grams of Cl needs which amount of Na?

Na amount $= \frac{38 \cdot 23}{35.5}$ which is $= 24.62$ grams.

It means after the reaction you will have $40 - 24.62 = 15.38$ grams of sodium (left).

You produce 1.07 mol of table salt. Its weight is $1.07 \cdot 58.5 = 62.62$ grams.
