Answered by ashaek123

Step-by-step explanation:

About 0.70 grams of copper will go with 8 grams gold to give you 8.70 grams of 22K rose-ish gold. But traditionally, you should not mix all copper in gold, but use a 60/40 AgCu (Silver-Copper) alloy to retail the yellowish color & not make it copperish.
