How do you calculate the mass of iron that can be extracted from 1000 kg of iron oxide?
1 Answer
- [(2×56)+(3×16)]g→(2×56)g.
- 160g→112g.
- 1g→112160g.
- 1kg→112160kg.
- 1000kg→112160×1000kg.
- =700kg.
What’s the mass of iron?
55.845 u
Iron/Atomic mass
What is the mass of iron III oxide and aluminum?
Hence 1 mole iron(III)oxide requires 2 moles aluminium. Therefore by ratio and proportion, 0.25mol iron(III)oxide requires 0.50 moles aluminium. This corresponds to a mass of : mAl=n×Mr=0.50×27=13.5g .
What mass percent of iron does fe3o4?
72.359 percent
The mass percent of iron in an oxide of iron with the formula Fe3 O4 is 72.359 percent.
What is the mass percentage of iron?
Mass percent composition of Fe = 16.96\%
What is the mass of 10kg of iron III oxide?
Iron III Oxide is Fe2O3. The molar mass is 2 x 55.845 + 3 x 16 = 159.69 g/mol So, the iron is 111.69 / 159.69 = 0.6994 times the mass of Fe2O3. 10kg of iron would require 10/0.6994 = 14.298kg of Fe2O3
What is the mass of iron in 240 tonnes of Fe2O3?
So, the mass of iron in 240 tonnes of Fe2O3 is 0.70×240 = 168 tonnes. There are more complicated ways of determining this, but they are needless complications!
What is the formula for ferric oxide?
Iron (III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron (II) oxide (FeO), which is rare; and iron (II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite.
What is the molecular weight of iron and oxygen in grams?
It is 159.68 grams per mole. You can easily calculate by adding together the weight of the atoms in the compound. An individual atom of iron is 55.84 g/mol and there are two in the compound so just double it. The single atoms of oxygen are 15.99 g/mol so with 3 in the compound just triple it.
