Question

If I want to make 100.0 g of my own salt (because I can and that's how I roll), how much elemental chlorine would I need?

Answer 1

We need 60.66 grams of chlorine to make 100 grams salt

Step-by-step explanation:

Step 1: Data given

Mass of salt (NaCl) = 100.00 grams

Molar mass of NaCl = 58.44 g/mol

Molar mass of Cl- = 35.45 g/mol

You also know that for every mole of NaCl you have 1 mole of Na because every molecule of NaCl has 1 atom of Na.

Step 2: Calculate mass of Chlorine needed to make 100 grams of NaCl

Mass Cl = 100(g NaCl) * 1 mol (NaCl)/58.44 g (NaCl) * 1 mol (Cl)/ 1 mol (NaCl) * 35.45 (g of Cl/ 1 mol (Cl)

Mass Cl = 60.66 grams (this means we need 39.34 grams of sodium)

We need 60.66 grams of chlorine to make 100 grams salt

Answer 2

60.7g of elemental chlorine

Step-by-step explanation:

Equation of reaction:

Na + Cl = NaCl

From the equation above,

1 mole (58.5g) of sodium chloride (salt) is formed from 1 mole (35.5g) of elemental chlorine

100g of salt would be produced from (35.5×100g)/58.5 elemental chlorine = 60.7g of elemental chlorine
