Question
these are questions about this experimentt(This experiment will involve determining the overall composition of an Al-Cu mixture, heating it
in a ceramic crucible to temperatures expected to result in a single-phase liquid, and then
allowing the liquid to cool until it freezes. ), please answer them, the diagram is provided.please note that the initial mass of aluminum is 94.14 grams and inital mass of cu is 21.52 grams, if you need any more information let me know. will give thumbs up.
