Question

Calculate the mass of iron which will be produced from 640 tonnes of haematite

Answer 1

Explanation:

Calculate the amount of iron that can be extracted from 2000 tonnes of haematite. ( Relative atomic masses: O = 16; Fe = 56).

Answer 2

Answer:

448 tonnes

Explanation: A mole of hematite gives 2 moles of iron. You can use the equation to see this.

1 mole of hemalite equals 160 grams and 2 moles of iron would mean 112 grams.

So

160/112 = 640 tonnes/x

And after doing the math, we get

x = 448 tonnes
