Answer:
Mass = 27.4 g
Explanation:
Given data:
Mass of sulfur = 15.7 g
Mass of iron = ?
Solution:
Chemical equation:
Fe + S → FeS
Number of moles of sulfur:
Number of moles = 15.7 g/32 g/mol
Number of moles = 0.49 mol
Now we will compare the moles of sulfur with iron
S : Fe
1 : 1
0.49 : 0.49
Mass of iron:
Mass = number of moles × molar mass
Mass = 0.49 mol× 55.85 g/mol
Mass = 27.4 g
