Question

10000 tonnes of iron reacted in a blast furnace Fe2O3 calculate the typical mass of iron produced each day

Answer 1

The easy way to do this is
Step 1. 2Fe2O3 + 3C ==> 3CO2 + 4Fe

Step 2. Then don't worry about the tonnes.

Step 3. mols Fe2O3 = 10,000/molar mass Fe2O3.

Step 4. Using the coefficients in the balanced equation, convert mols Fe2O3 to mols Fe.

Step 5. Then grams Fe = mols Fe x atomic mass Fe and the answer will come out in tonnes if you started with tonnes.

You can do it the long way by changing 10,000 tonnes to grams, following Steps 3, 4, and 5 to come up with grams Fe, and add a step 6 to convert grams back to tonnes.
The answer should be the same either way.
