Your question is garbled. It sounds like you've blurred together 3 different questions. Try asking it one piece at a time.

The first portion of the question is all that I can understand. If the 5.25% is designated as weight percent, then the 200 lb chunk of alloy contains

200 * 0.0525 = 10.5 lb

After that, it is too garbled for me to be of any help

For a question to be answered, it has got to be clear and unambiguous. What do you want from us? It looks like a amalgamation of three questions.
