<span>0.453 moles O2 is the solution</span>
Since there are 63.01284 grams to one mole of HNO3, then 12.5 moles would be in 450 grams of it.
1128 is the momentum for this. i think
Oxygen = 16
Iron = 55.8
16 x 27.6% = 4.4 /4 = 1.1
55.8 x 72.4% = 40.4 /4 = 10.1
1 oxygen and 10 iron, so Fe10 O
Answer:
I think the answer is c!
