Question

How many grams of 40% pure FeO can produce 5. 6g Fe according to given equation (At. Wt. Of Fe = 56)

FeO + CO = Fe + CO2

Answer 1

First, let's calculate the molar mass of FeO. That's 56 (Fe) + 16 (O) = 72 g/mol. Now, from the balanced equation, 1 mol of FeO gives 1 mol of Fe.

So, 72 g of FeO gives 56 g of Fe.

To produce 5.6 g of Fe, you need (5.6/56) * 72 = 7.2 g of pure FeO.

But the FeO you have is only 40% pure. So, you need 7.2 / 0.40 = 18 g of the 40% pure FeO to produce 5.6 g of Fe.
