How many grams of sodium chloride are needed to make 17.5g of sodium?

Answer : The mass of needed are, 44.5 grams.

Explanation :

First we have to calculate the moles of Na.

Now we have to calculate the moles of NaCl.

The balanced chemical reaction is:

From the reaction, we conclude that

As, 2 mole of produces from 2 mole of

So, 0.761 mole of produces from 0.761 mole of

Now we have to calculate the mass of

Molar mass of = 58.5 g/mole

Therefore, the mass of needed are, 44.5 grams.
