Calculate the mass (in kg) of each compound that contains 1.0 x 10E3 kg of iron.

Fe2O3
I really can't figure this one out please help step by step

See your post above.

To calculate the mass of each compound that contains 1.0 x 10^3 kg of iron, we need to know the molar mass of each compound and the moles of iron present in each compound.

1. Start by understanding the given compound, Fe2O3. This compound consists of two iron (Fe) atoms and three oxygen (O) atoms.

2. Next, determine the molar mass of each element. The atomic mass of iron (Fe) is approximately 55.85 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol.

3. Calculate the molar mass of Fe2O3 by adding up the atomic masses of each element in the compound, considering their respective subscripts:

Fe2O3: (2 x 55.85 g/mol) + (3 x 16.00 g/mol) = 159.70 g/mol

4. Use the molar mass to find the moles of iron (Fe) in 1.0 x 10^3 kg of iron. Convert the given mass of iron to grams by multiplying it by 1000:

1.0 x 10^3 kg x 1000 g/kg = 1.0 x 10^6 g

5. Now, use the molar mass of Fe2O3 to calculate the moles of Fe in the given mass of iron. Use the following ratio:

1 mol Fe2O3 = 2 mol Fe

Moles of Fe = (1.0 x 10^6 g Fe) / (2 x 55.85 g/mol Fe2O3)

6. Finally, convert the moles of Fe to mass by multiplying it by the molar mass of Fe:

Mass of Fe = (moles of Fe) x (molar mass of Fe)

Note: Steps 4-6 can be replicated for calculation of the other compound(s) containing iron.

Using the above steps, you can now calculate the mass (in kg) of each compound that contains 1.0 x 10^3 kg of iron.
