1:2:3.

## What is the mole iron oxygen ratio?

A second example: Iron combines with oxygen to form a compound called “ferrous oxide”. The ratio of mass of oxygen to iron is 0.2865.

## What is the percentage of iron in iron III oxide?

Iron(III) oxide is 69.94% iron by mass.

## What is the mole ratio of fe304 to Fe?

2) In the case of Fe3O4 and Fe, the chemical equation is: Fe+H2O → Fe3O4+H2. 4) From that the mole ratios are: 3 mol Fe : 4 mol 4H2O : 1 mol Fe3O4 : 4 mol H2.

## What is the mole mole ratio of KClO3 o2?

You’d need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you’ll always produce 3/2 times more moles of the latter.

Therefore, 3 moles of KClO3 will produce = (3 x 3) /2 = 4.5moles of O2.

## What is the mole ratio of pcl3 to pcl5?

Answer : The mole ratio of to is 1 : 1 ratio.

## Do you reduce mole ratios?

The molar ratio can be constructed using any two compounds in the reaction, be they reactants or products. Write the molar ratios for (a) O2 to SO3 and (b) SO2 to SO3. … Note that both ratios can be reduced.

## What is the mole ratio?

A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction. The numbers in a conversion factor come from the coefficients of the balanced chemical equation.

## What is the formula weight for iron III oxide in amu?

Iron(III) oxide is one of the two major iron oxides. It has the chemical formula Fe2 O3 and is reddish-brown in color, which makes it useful in pigments for cosmetics and paints. The molar mass of iron(III) oxide is approximately 159.7 g/mole and is insoluble in water.

## What is the percentage of iron in iron III chloride fecl3?

Percent composition by element

Element Symbol Mass Percent
Chlorine Cl 65.571%
Iron Fe 34.429%

## Which ore has the highest iron content?

Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower.
