Question

4 Fe + 3 02- 2 Fe203
o How many grams Fe2O, will be produced if
you start with 170 g Fe?

Answer 1

243.05 gm of Fe2O3

Step-by-step explanation:

From periodic table mole wt of Fe = 55.845 gm

170 g / 55.845 gm/mole = 3.044 moles Fe

From equation

4 Fe ====> 2 Fe2 O3

so 1/2 as many moles as Fe 3.044 / 2 = 1.522 moles of Fe2O3

mole wt of Fe2 O3 from periodic table = 159.687 gm/mole

1.522 moles * 159.687 gm/mole = 243.05 gm
