Answer:
666.22grams
Explanation:
The balanced chemical equation of this reaction is given as follows:
2Na + Cl2 → 2NaCl
Based on the above equation, 1 mole of Chlorine gas (Cl2) is needed to produce 2 moles of sodium chloride (NaCl).
Therefore, 5.7moles of Cl2 will react to produce (5.7 × 2) = 11.4moles of NaCl.
Note that, the mass of NaCl was asked in this question. We find the mass of NaCl from the mole by using the formula;
moles = mass/molar mass
Molar mass of NaCl = 58.44 g/mol
11.4 = mass/58.44
mass = 58.44 × 11.4
mass = 666.22grams.
