1 Answer. 1.0 mol Fe2O3 contains 111.69 g Fe .
What is the total mass of 1 mole of Fe2O3?
The molar mass of Fe2O3 is 159.7 g/mol.
How many moles of iron can be made from Fe2O3?
8.57 g Fe2O3 1 mol Fe2O3 | 4 mol Fe = 0.107 mol Fe | 159.70 g Fe2O3 2 mol Fe2O3 Page 4 10.
How do you find the moles of Fe in Fe2O3?
The molar mass of Fe is 55.845 grams (1 mole Fe = 55.845 grams Fe). The molar mass of O2 is 2 x 16.00 or 32.00 grams (1 mole O2 = 32.00 grams O2). The mass of a mole of Fe2O3 is (2 x Fe) + (3 x Oxygen) = (2 x 55.845) + (3 x 16.00) = 159.69 grams (1 mole of Fe2O3 = 159.69 grams Fe2O3).
What is the mass of one mole of iron Fe?
The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.
What is the percentage of Fe2O3?
|Percent Composition of iron (III) oxide, Fe2O3:Step 2a & b||% Fe = 111.70g/159.70g X 100% = 69.944% 2b. % O = 48.00g/159.70g X 100% = 30.06%|
What is the mass of 5 moles of Fe2O3?
2. What is the mass of 5 moles of Fe2O3 ? Smal x 159.0 1798.45g Page 2 3.
How many moles of iron are produced?
Iron has a molar mass of 55.84 grams/mole. So, five grams divided by 55.84 grams/mole gives us 0.089 moles of iron.
How many water molecules are in 5.2 moles water?
Answer. There are therefore 6.02 × 1023 water molecules in a mole of water molecules.
How many particles are in one mole of anything?
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.
How do you calculate Fe2O3?
A factor is the sum of the atomic weights of the elements in the required formula divided by the sum of the atomic weights in the original formula. The factor to convert Fe2O3 to 2FeO is 2 x (55.85 + 16)/(55.85 x 2 + 16 x 3) = 0.8998 while the factor to convert 2FeO to Fe2O3 is 1/0.8998 = 1.1113.
How many moles contain 1 kg of Fe?
Answer: Moles of iron for the given amount is 17.90 moles.
How do you convert Fe2O3 to FE?
To get FeO to Fe2O3 just multiply FeO by 1,11111… Fe2O3 to FeO is just reverse, divide Fe2O3 by 1,11111 (or multiply by 0,899999 as said above).
How many molecules are in a mole?
Avogadro’s Number and the Mole. The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.
How many atoms are in a mole of oxygen?
One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms.
What is the mass of 1 mole of o2?
The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.
