Aluminum bronze contains 92.0% copper and 8.0% aluminum. what maximum mass of aluminum bronze can be prepared from 73.5g of copper and 42.2g of aluminum? initially i tried dividing 73.5g by 0.92, and i thought i have found the max mass of aluminum bronze. but then i tried using 70.0g of copper which gave me a result of about 82.17g of total mass of aluminum bronze. how should i calculate it accurately so that i can maximize the use of both metals?
