Question

If 5.7 mol Cl2 reacts with Na , how many grams of NaCl could be formed? The

molar mass of NaCl is 58.44 g/mol

Answer 1

666.22grams

Step-by-step 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.
