Calculating the Mass of Copper and Zinc in a 2kg Alloy

To calculate the mass of copper and zinc in a 2kg alloy consisting of 5 parts copper and 3 parts zinc, we can use the following approach:

1. Calculate the Total Parts of the Alloy: - The total parts in the alloy are 5 (copper) + 3 (zinc) = 8 parts.

2. Calculate the Mass of Copper: - The mass of copper in the alloy can be calculated as (5/8) * 2kg = 1.25kg.

3. Calculate the Mass of Zinc: - The mass of zinc in the alloy can be calculated as (3/8) * 2kg = 0.75kg.

Therefore, the mass of copper in the 2kg alloy is 1.25kg and the mass of zinc in the 2kg alloy is 0.75kg.
