An iron ore contains 35% Fe2O3 by mass.
I wouldn't dream of not taking it.It seems to be your oldest and dearest friend.How many nights has your friend brought you comfort and stayed close till you felt much better?This is very sweet.most of us only wish we had a friend so dear.
Take it definately. I still have my teddy bear and I am 34, I have since passed it on to my kids, but I am SOOO glad I kept it because my mom died right before I got pregnant and it gave me a connection for my kids to her because we (my mom and I) had special talks with him every night.
There's no reason why you should get rid of it. I have baby blankets that were my mom's. Keep it as a memory of your childhood.
After separating off the 65% gangue minerals from the iron ore, one is left with 14.6 x 0.35 kg 5.11 kg of Fe2O3 Going to the Periodic table, we know that iron has an atomic weight of 56 oxygen has an atomic weight of 16. That gives Fe2O3 an molecular weight of (56 x 2) + (16 x 3) 112 + 48 160. The proportion of iron in Fe2O3 (56 x 2) / 160 112 / 160 0.7 or 70% 0.7 x 5.11 kg of Fe2O3 3.577 kg Therefore the maximum weight of iron that can be recovered 3.577 kg
