Round to The Manufacture of Fresh or chilled.
In order to Manufacture of 150 g Fresh or chilled will be 70 g Sodium Provided, The with Chlorine to Sodium chloride reacting to be. What ? Weight remaining From the Sodium after (Stoichiometric) Application remaining?

---

Lösung:

The Balanced reaction equation is:
2 Na + Cl₂ → 2 NaCl

Manufacture	M(g/mol)	m(g)	n(mol)
NaCl	58.5	150	150 / 58.5 = 2.56
Na	23	58.9	2.56
Cl2	71	91.0	2.56 / 2 = 1.28

Es will be 58.9 g Na used, remaining Staying So what do you mean? 70-58.9 = 11.1 Grams

Additional information: It 's will be In total 91 Grams Chlorinated gases, Cl₂, for The reaction Required.
