Inquiry Lab #1

Goal:  Determine the Mass Percent of Copper Metal in a Unknown Sample of Brass


Key concepts that must be addressed:
How do you remove the copper from the brass?
How do you determine the “amount” of copper that was removed from the brass?

Consider the data collected and how that will be helpful –

Remember – Mass % of Copper in Brass = (Mass of Copper/Mass of Brass)X100%

Requirement – You must incorporate the Spectrophotometer in your procedure




Come to class with thoughtful ideas.  DO NOT LOOK UP THE GOAL ONLINE.  The idea is for you to think, not find the answers on the internet.  If you want to look up information that is needed, like “how to remove copper from brass” ok.
