A copper ore body contains 8% copper by weight. If 2 tonnes of ore are processed, how many kilograms of pure copper can be obtained?

Step-by-step solution

1. Convert 2 tonnes to kilograms: $2,\text{t}=2000,\text{kg}$.
2. Calculate 8% of 2000 kg: $0.08\times 2000=160$ kg.
3. Thus, 160 kg of pure copper can be extracted.
