Question

The karat scale used to describe gold alloys is based on
mass percentages. (a) If an alloy is formed that is 50 mol%
silver and 50 mol% gold, what is the karat number of the
alloy? Use Figure 12.18 to estimate the color of this alloy.
(b) If an alloy is formed that is 50 mol% copper and 50
mol% gold, what is the karat number of the alloy? What is
the color of this alloy?
