Magnetic iron ore is Fe3O4. WHat mass of iron is in 1000. kg of this ore?
rotate your tires then by a whole new set when you get back.
no if there is tread left then your good if there is metal chord showing then you need to replace it provided that the tire is wearing evenly then you should not have a problem
Find the percent weight of Fe in the compound first. To do this, add up all the molecular masses (3x the mass of iron)+(4c the mass of oxygen) And then divide just the weight of iron by the total weight. This gives you the %weight of iron. Then multiply 1000.0kg by the percent to get the weight of iron.
