Calculate the mass of iron reacted with sulfur if 44 g of iron sulfide is formed 3.

The mass of sulfur sulfide is 44 g.

Determine the mass of the iron that has reacted.

First, you need to write down the reaction equations.

2Fe + 3S = Fe2S3.

Let’s calculate the molar mass of iron.

M (Fe) = 56 g / mol.

Let’s calculate the molar mass of iron sulfide.

M (Fe2S3) = 2 * 56 + 32 * 3 = 208 g / mol.

Next, we determine the mass of iron according to the reaction equation.

X g of iron – 44 g of iron sulfide.

2 * 56 g / mol Fe – 208 g / mol Fe2S3.

X = 2 * 56 * 44/208 = 24 g.

The mass of iron is 24 grams.

Answer: m (Fe) = 24 g.
