You are given 600 grams of sodium chloride (NaCl), but you are planning to purify the substance and extract just the sodium. How many moles of Na can you theoretically extract from 600 grams of NaCl? Explain your reasoning.

Moles of Na theoretically extract : 10.256

Given

600 g of NaCl

Required

moles of Na

Solution

Na can be electrolyzed from NaCl(molten)

Na⁺ + e⁻⇒ Na

Cl⁻⇒1/2 Cl₂ + e⁻

Overall reaction :

NaCl⇒Na + 1/2 Cl₂ x2

2NaCl⇒2Na + Cl₂

mol of NaCl(MW=58.5 g/mol) :

= 600 g : 58.5 g/mol

= 10.256

From the equation, mol ratio of NaCl : Na = 2 : 1, so :

mol Na = mol NaCl = 10.256

"the periodic table is arranged in order of atomic number."
