Answer:

The answer to your question is 576 grams of FeO

Step-by-step explanation:

Balanced chemical reaction

2Fe + O₂ ⇒ 2 FeO

Reactant Elements Products

2 Fe 2

2 O 2

Data

mass of FeO = ?

moles of Fe = 8

Excess Oxygen

Process

1.- Convert moles of Fe to grams

Atomic mass = 56 g

56 g of Fe ------------------ 1 mol

x ------------------ 8 moles

x = (8 x 56) / 1

x = 448 g of Fe

2.- Use the coefficients of the balanced reaction to find the grams of FeO.

Molecular mass of FeO = 2[ 56 + 16]

= 144 g

2(56) g of Fe ----------------------- 144 g of FeO

448 g ----------------------- x

x = (448 x 144) / 2(56)

x = 64512 / 112

x = 576 grams of FeO
