What will be the mass of ferrous sulphide formed when 20 gram of pure sulphur reacts with iron ?
What type of solid is Ne? Metallic? Molecular? Ionic? or Covalent Network?
Fe + S ==> FeS
mols S = grams/atomic mass S = ?
Convert mols S to mols FeS. Look at the equation. See that 1 mol S forms 1 mols FeS.
Then grams FeS = mols FeS x molar mass FeS.
I responded to your question above. Please don't post questions piggy back. Most of that type never gets and answer.
To determine the mass of ferrous sulfide formed when 20 grams of pure sulfur reacts with iron, we need to consider the balanced chemical equation for the reaction between iron and sulfur.
The balanced equation for the reaction is:
Fe + S → FeS
According to the equation, one mole of iron (Fe) reacts with one mole of sulfur (S) to produce one mole of ferrous sulfide (FeS).
To find the mass of ferrous sulfide formed, we can follow these steps:
Step 1: Find the molar mass of sulfur (S)
The molar mass of sulfur is 32 grams/mol.
Step 2: Calculate the number of moles of sulfur used
Using the formula: moles = mass/molar mass
moles of sulfur = 20 grams / 32 grams/mol
moles of sulfur = 0.625 mol
Step 3: Determine the mass of ferrous sulfide formed
Since the balanced equation indicates a 1:1 molar ratio between sulfur and ferrous sulfide, the moles of ferrous sulfide formed will also be 0.625 mol.
Now, to find the mass of ferrous sulfide, we need to multiply the number of moles by the molar mass of ferrous sulfide (FeS).
Step 4: Find the molar mass of ferrous sulfide (FeS)
The molar mass of iron (Fe) is 55.85 grams/mol, and the molar mass of sulfur (S) is 32 grams/mol. Therefore, the molar mass of ferrous sulfide (FeS) is 55.85 + 32 = 87.85 grams/mol.
Step 5: Calculate the mass of ferrous sulfide formed
mass of ferrous sulfide = moles of ferrous sulfide × molar mass of FeS
mass of ferrous sulfide = 0.625 mol × 87.85 grams/mol
mass of ferrous sulfide = 54.91 grams
Therefore, the mass of ferrous sulfide formed when 20 grams of pure sulfur reacts with iron is approximately 54.91 grams.
