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 depositsAnswer 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 Not sure what the "Answers" are?

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 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 Fecontained in BIF deposits

Answer x 10¹⁸ moles of Fecontained 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
