What mass of iron ore in kilograms will contain 15.64 grams of iron if the ore contains 0.257 iron by mass?
The mass of iron ore is 6,085 kg.
How much energy is contained in matter with a mass of 2 grams?
1.8e14 j
What is the mass in grams for 0.226 mole of Iron hydroxide?
It depends on whether it is iron (II) hydroxide or iron (III) hydroxide.
How many grams of iron can be found in a 130 g sample of iron III sulfide?
The formula of iron (III) sulfide is Fe2S3, showing that each formula unit contains two iron atoms. The gram formula unit mass for iron (III) sulfide is 207.87, and the gram atomic mass of iron is 55.847. Therefore, the fraction by mass of iron in iron (III) sulfide is 2(55.847)/207.87 or about 0.5373, and the grams of iron in 130 g of iron (III) sulfide is 0.5373 X 130 or 69.9 grams, to the justified number of significant digits.
What information does the molar mass gives?
It is the sum of the atomic weights of atoms contained in the molecule, expressed in grams.
What is the mass in grams of 1.40 mol of iron (III) sulfate'?
The mass in grams of 1,40 mol of anhydrous iron(III) sulfate is 559,832.
What mass of iron ore in kilograms will contain 15.64 grams of iron if the ore contains 0.257 iron by mass?
The mass of iron ore is 6,085 kg.
What is the mass of 4 moles of iron?
The mass of 4 moles of iron is 224 grams
How much energy is contained in matter with a mass of 2 grams?
1.8e14 j
What is the mass in grams for 0.226 mole of Iron hydroxide?

How many grams of iron can be found in a 130 g sample of iron III sulfide?
The formula of iron (III) sulfide is Fe2S3, showing that each formula unit contains two iron atoms. The gram formula unit mass for iron (III) sulfide is 207.87, and the gram atomic mass of iron is 55.847. Therefore, the fraction by mass of iron in iron (III) sulfide is 2(55.847)/207.87 or about 0.5373, and the grams of iron in 130 g of iron (III) sulfide is 0.5373 X 130 or 69.9 grams, to the justified number of significant digits.
How many grams is a sample containing 2.71 x 1024 atoms of iron?
Amount of Fe = (2.71x1024)/(6.02x1023) = 4.50mol The atomic mass of Fe is 55.8 Mass of Fe = 4.50 x 55.8 = 251g
What information does the molar mass gives?
It is the sum of the atomic weights of atoms contained in the molecule, expressed in grams.
What is the molar mass of a molecule?
The mass of one mole of substance, usually in grams or kilograms
If there are 3 grams of iron in a sealed container with most air the sealed container with iron moist air weighs a total 5 grams will there be 3 grams of rust if all the iron rusts?
No, iron oxide weighs more than pure iron. The iron will pick up the extra mass of the oxygen molecules that bond with it.
How many iron atoms present in 5.0 mol of iron metal?
Five iron atoms have a mass of 1.3155 x 10-22 grams.
What is the mass of iron that has density of 8.268?
8.268 grams per cubic centimetre! The total mass depends on the volume of course!
