BotEC: Percentage of Copper in Ore - Activity Collection

2021-7-18 · The copper ore forms only 0.7% of the rock. We need to find a number that we can multiply by .007 to get 90 kg. Dividing 90 kg by .007 will give us that number—approximately 12,860 kg. Multiplying that number by 2.2 pounds/kg would give us the number of pounds (about 28,300 pounds).
