What is the mass of 3.01 x 1023 formula units of Fe2O3?
The mass is approx. 80 g.
What is the mass of 0.7891 mol of ferric oxide Fe2O3?
Atomic mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g

The formula for rust can be represented by Fe2O3 How many moles of Fe are present in 14.2 g of the compound?
14.2g Fe2O3 (1mol Fe2O3/159.7g(2mol Fe/1mol Fe2O3) = 0.178 moles Fe
What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
How do you calculate the Fe content in FeO and Fe2O3?
Mass of Fe=(Mass of Fe2O3)(Mr Fe/ Mr Fe2O3)
What is the mass of 3.01 x 1023 formula units of Fe2O3?
The mass is approx. 80 g.
What is the mass of 0.7891 mol of ferric oxide Fe2O3?
Atomic mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g

Each molecule of iron oxide fe2o3 contains how many atoms of iron?
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
How many moles of Fe2O3 are in 251 g of the compound?
Adding together the mass of two irons and three oxygen.....,251 grams Fe2O3 (1 mole Fe2O3/159.7 grams)= 1.57 moles iron II oxide ( also known as ferric oxide )===================================
What is percent by mass of oxygen in Fe2O3?
To answer this question we will have to know which of the many oxides of iron you are targeting.
Is Fe2O3 is a molecular compound?
No, Fe2O3 is ionic
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.
You heat 3.970 g of a mixture of Fe3O4 and FeO to form 4.195 g Fe2O3 The mass of oxygen reacted is?
