Given information
In the given question we are asked to calculate the mass percent composition of iron for each of these iron ores such as,, and
Iron is mined from the earth as iron ore. Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent.
Step-by-step explanation
Step 1.
We will calculate the composition of iron in each of these compounds.
as we know that,
Mass percent composition of iron for each of these iron ores are.
the total mass of iron is
1. hematite, is a common iron oxide compound with the formula and is widely found in rocks and soils.
we are going to calculate the total mass percent of Iron in .
=
Hence, the composition of Iron in is .
