You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: How many atoms of iron are there in 2.01 moles of each of the following? WebSep 22, 2014 · Let a equal the number of iron atoms, b equal the number of sulfur atoms, and c equal the number of oxygen atoms. Iron increases its oxidation state by 1, sulfur by 5, and oxygen decreases by 2. So: 1a + 5b - 2c = 0. We also know that iron and sulfur are in a 1:2 ratio because they come from pyrite. 2 a = b . Substitution yields: 1a + 5(2a ...
