Answer:

51.57 g.

Explanation:

  • The balanced equation: 2Fe + 3S → Fe₂S₃, it is clear that 2.0 moles of Fe react with 3.0 moles of S to produce 1.0 mole of Fe₂S₃.
  • We need to calculate the no. of moles of Fe₂S₃:

n = mas/molar mass = (96.0 g)/(207.9 g/mol) = 0.46 mol.

Using cross multiplication we can get the no. of moles of Fe that isn eeded to produce 0.46 mol of Fe₂S₃:

2.0 moles of Fe produces → 1.0 mol of Fe₂S₃.

??? moles of Fe produces → 0.46 mol of Fe₂S₃.

∴ The no. of moles of Fe needed = (2.0 mol)(0.46 mol)/(1.0 mol) = 0.92 mol.

  • Now, we can get the mass of 0.92 mol Fe:

mass = no. of moles x molar mass = (0.92 mol)(55.845 g/mol) = 51.57 g.

The study of chemicals and bonds is called chemistry.

The correct answer to the question is 51.57 g.

What is mass?

  • Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied.
  • An object's mass also determines the strength of its gravitational attraction to other bodies.

The balanced equation is as follows:

  • [tex]2Fe + 3S ----> Fe_2S_3[/tex]

it is clear that 2.0 moles of Fe react with 3.0 moles of S to produce 1.0 mole of[tex] Fe_2S_3.[/tex]

  • The no. of moles of Fe₂S₃:

[tex]n = \frac{mass}{molar mass}\\ = \frac{(96.0 g)}{(207.9 g/mol)}\\ = 0.46 mol.[/tex]

Hence, 2.0 moles of Fe produces → 1.0 mol of Fe₂S₃.

The no. of moles of Fe needed

[tex] = \frac{(2.0 mol)(0.46 mol)}{(1.0 mol)} = 0.92 mol. [/tex]

Now, we can get the mass of 0.92 mol Fe:

Therefore,

[tex]mass = no. \ of\ moles * molar\ mass\\ = (0.92 mol)(55.845 g/mol)\\ = 51.57 g.[/tex]

Hence, the correct answer is 51.57.
