Answer:
The balanced equation for the reaction is as follows;
2Fe + 3S ---> Fe₂S₃
molar ratio of Fe to Fe₂S₃ is 2:1
mass of Fe₂S₃ to be produced is - 96 g
therefore number of moles of Fe₂S₃ to be produced is - 96 g / 208 g/mol
number of Fe₂S₃ moles = 0.46 mol
according to the molar ratio
when 2 mol of Fe reacts with 3 mol of sulfur then 1 mol of Fe₂S₃ is produced
that for 1 mol of Fe₂S₃ to be produced - 2 mol of Fe should react
therefore for 0.46 mol of Fe₂S₃ to be produced - 2 x 0.46 = 0.92 mol of Fe is required
mass of Fe required - 0.92 mol x 56 g/mol = 51.5 g
mass of Fe required is - 51.5 g
Explanation:
Answer: 51.69g
Explanation:
2Fe + 3S —> Fe2S3
Molar Mass of Fe2S3 = (2x56) + (32x3) = 112 + 96 = 208g/mol
Molar Mass of Fe = 56g/mol
Mass conc. Of Fe = 2x56 = 112g
From the equation,
112g of Fe produced 208g of Fe2O3.
Therefore, Xg of Fe will produce 96g of Fe2O3 i.e
Xg of Fe = (112x96)/208 = 51.69g
