Quick Answer: How many moles of Fe3O4 are formed?

Contents

How many moles are in Fe3O4?

These relative weights computed from the chemical equation are sometimes called equation weights. moles of Fe = mass/molar mass = 67/56 = 1.196. moles of Fe3O4 that can form from this 1.196 x 1/3 = 0.399 moles, since mole ratio of Fe : Fe3O4 = 3:1.

How many moles are in 1g of Fe2O3?

The molar mass of Fe2O3 is 159.7 g/mol. 2. The molar mass of AgNO3 is 169.9 g/mol.

How do you convert grams to moles calculator?

To correctly estimate the number of moles, n , of a substance of a specific mass, m , (in grams), you need to follow the grams to moles formula: n = m / M , where, M is the molar mass of this material.

How many grams are in 3 moles of Na2SO4?

No of moles=458/142=3 moles. There are 3 moles in 458 grams of Na2SO4.

Is Fe3O4 acidic or basic?

The microwave hydrothermally treated Fe3O4 particles were basic at pH <7.7 and acidic at pH >7.7, while the nontreated and base-treated particles did not show clear acidic or basic nature.

What is the formula of rust?

Rust is apparently a hydrated form of iron(III)oxide. The formula is approximately Fe2O3•32H2O, although the exact amount of water is variable.

What are the elements in Fe3O4?

Fe3O4 is the chemical formula of Iron (II, III) oxide which has four oxygen atoms, three iron atoms. The bond formation between iron and oxygen depends on the difference in electronegativity between them. Iron (Fe) is metal and oxygen(O2) is non-metal.
