Answer:

0.04 moles

Explanation:

Given data:

Mass of Fe = 2.30 g

Moles of FeCl₃ produced = ?

Solution:

Chemical equation:

2Fe + 3Cl₂         →     2FeCl₃

Number of moles Fe:

Number of moles = mass/molar mass

Number of moles = 2.30 g/ 55.85 g/mol

Number of moles = 0.04 mol

now we will compare the moles of iron and iron chloride.

             Fe            :           FeCl₃

              2            :              2

            0.04        :           0.04

Thus, 0.04 moles of iron chloride are produced.

The number of moles that could be produced is 0.04 moles

  • The calculation is as follows:

Chemical equation:

2Fe + 3Cl₂         →     2FeCl₃

Number of moles Fe:

It should be

[tex]= mass\div molar mass\\ = 2.30 g\div 55.85 g/mol [/tex]

= 0.04 mol
