Coke is an impure form of carbon that is often used in the in- dustrial production of metals from their oxides. if a sample of coke is 95% carbon by mass, determine the mass of coke needed to react completely with 1.0 ton of copper(ii) oxide.

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.

Explanation:

1 Ton = 907185 grams

Mass of copper oxide = 1.0 Ton = 907185 grams

Moles of copper oxide =

According to reaction, 2 moles of copper oxide reacts with 1 mole of carbon.

Then 11403.95 moles of copper oxide will react with:

of carbon

Mass of 5,701.98 moles of carbon:

Mass of coke = x

Mass of carbon = 68,423.75 g

Percentage of carbon in coke = 95%

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.
