Answer:
2522g
Explanation:
8Fe + S8 —> 8FeS
From the question,
8moles of Fe required 1mole of S8.
Therefore, Xmol of Fe will require 5.65mol of S8 i.e
Xmol of Fe = 8 x 5.65 = 45.2moles
Now we need to covert 45.2moles to gram. This is illustrated below below:
Molar Mass of Fe = 55.8g/mol
Number of mole of Fe = 45.2moles
Mass of Fe =?
Mass = number of mole x molar Mass
Mass of Fe = 45.2 x 55.8
Mass of Fe = 2522g
Therefore, 2522g of Fe is needed for the reaction.
The solubility of gaseous solutes in liquid solvents is greater when the solvent is colder.
