What is the mass of 9.871023 formula units of aluminum oxide?
Assuming that the number "9.871023" would or should have been written as "9.87 X 1023" if the typographical resources to do so were available to the questioner: Avogadro's Number, which is the number of formula units in a mole of any material, is about 6.022 X 1023. The gram formula mass for aluminum oxide is 101.96. Therefore, the mass of the stated number of formula units of aluminum oxide is: 101.96(9.87/6.022) or about 164 grams, to the justified number of significant digits.
How many formula units are in .671 moles of iron III sulfate?
One formula unit of iron III sulfate consists of one iron atom, three sulfur atoms, and 12 oxygen atoms.

How many moles of Fe2O3 is present in 150.0g of Fe2O3?
To convert grams to moles you use the molar mass of iron (55.8 grams per mole). Divide the numbers to get the number of moles: 500 g Fe / 55.8 g/mol = 8.96 mol Fe. To calculate the number of atoms, use Avogadro's Number (6.02*1023). Multiply the number of moles and Avogadro's number: 8.96 mol * (6.02*1023) = 5.39*1024 Fe atoms.

What is the mass of oxygen in Fe2O3 when the formula mass of Fe2O3 is 160 amu?
In the formula Fe2O3, there are two iron (Fe) atoms and three oxygen (O) atoms. The molar mass of iron is approximately 56 amu, so the mass contributed by iron is 2 × 56 amu = 112 amu. Therefore, the mass of oxygen in Fe2O3 is the total formula mass (160 amu) minus the mass of iron (112 amu), which equals 48 amu. Thus, the mass of oxygen in Fe2O3 is 48 amu.
