Now, let us think about iron (Fe). The total mass of BIFs globally is estimated at 5.0×1017 kg, wherein iron accounts for approximately 35% by mass. The atomic mass of iron is 55.8 g/mole (0.0558 kg/mole). What is the total mass of iron in BIFs in kilograms and moles? Answer x 1017 kg of Fe contained in BIF deposits Answer x 1018 moles of Fe contained in BIF deposits

Question
Now, let us think about iron (Fe). The total mass of BIFs globally is estimated at 5.0×1017 kg, wherein iron accounts for approximately 35% by mass. The
Answer x 1017 kg of Fe contained in BIF deposits
Answer x 1018 moles of Fe contained in BIF deposits
Finally, take the values you have computed in units of moles, and express them as the molar ratio of iron (Fe) to oxygen (O2) of BIFs. You can do this by dividing both sides of the ratio by the larger number (Fe in this case).
Fe:O2 = 1:Answer
