A type of brass is made by combining copper and zinc in an 8:2 ratio. If you want to make 2 kg of brass, how many grams (g) of copper do you need? Super Al Upgrade to exceed 90% accuracy

## Step 1:The problem tells us that brass is made by combining copper and zinc in an ratio. This means for every 8 parts of copper, we have 2 parts of zinc. ## Step 2:To calculate the amount of copper required to make 2 kg of brass, we first need to understand that the total ratio is \(8 (for copper) + 2 (for zinc) = 10\) parts. The ratio of copper to the total amount of brass is therefore .## Step 3:We want to find 'x', where x is the amount of copper needed for 2000g (equivalent to 2 kg) of brass. We can set up the proportion as follows:### \(x (weight of copper) : 2000g (total weight of brass) = 8 (parts of copper) : 10 (total parts)\)## Step 4:By cross multiplication, we can solve for x:### \(x = (8/10) * 2000 = 1600g\)Therefore, 1600g of copper are required in order to make 2kg of brass under the given ratio.
