How much substance and mass of iron is required to react with 16 g of sulfur?

This chemical reaction involves the same amount of sulfur and iron.
Let’s find the amount of the substance contained in 16 grams of sulfur.
To do this, we divide the mass of sulfur by its molar mass.
M S = 32 grams / mol;
N S = 16/32 = 0.5 mol;
The amount of iron substance will also be equal to 0.5 mol.
Let’s find its mass.
M Fe = 56 grams / mol;
m Fe = 0.5 x 56 = 28 grams;
