What is the mass of iron sulfide (||) formed as a result of the interaction of 112 g of iron with sulfur

1. Let us write down the reaction equation for obtaining iron sulfide (2):

Fe + S = FeS;

2.Calculate the chemical amount of iron:

n (Fe) = m (Fe): M (Fe) = 112: 56 = 2 mol;

3.The amounts of sulfide and iron according to the equation are related as 1: 1:

n (FeS) = n (Fe) = 2 mol;

4.Let’s find the mass of the resulting iron sulfide:

m (FeS) = n (FeS) * M (FeS);

M (FeS) = 56 + 32 = 88 g / mol;

m (FeS) = 2 * 88 = 176 g.

Answer: 176 g.
