Question
An ore contains 7.8% aluminium. What mass of aluminium would there be in 50kg of the ore?
Solution
To find the mass of aluminium in 50kg of the ore, you need to follow these steps:
-
Convert the percentage of aluminium to a decimal by dividing it by 100. So, 7.8% becomes 0.078.
-
Multiply the mass of the ore by the decimal to find the mass of the aluminium. So, 50kg * 0.078 = 3.9kg.
Therefore, there would be 3.9kg of aluminium in 50kg of the ore.
