Answer 2

Calculating the Iron Content in FeO

To calculate the iron content in the compound FeO, we can use the molar masses of iron (Fe) and oxygen (O) to determine the percentage composition of iron in FeO.

The molar mass of Fe is approximately 55.845 g/mol, and the molar mass of O is approximately 15.999 g/mol.

Using these molar masses, we can calculate the percentage composition of iron in FeO.

The formula for calculating the percentage composition of an element in a compound is:

Percentage Composition = (Atomic Mass of Element / Molar Mass of Compound) x 100

Substituting the values for Fe and O into the formula, we get:

Percentage Composition of Iron in FeO = (55.845 / (55.845 + 15.999)) x 100

Calculating this gives us the percentage composition of iron in FeO.

Let's calculate the percentage composition of iron in FeO using the given molar masses.

Percentage Composition of Iron in FeO = (55.845 / (55.845 + 15.999)) x 100 = 77.73%

So, the percentage composition of iron in FeO is approximately 77.73%.
