Step 1
The density of an alloy can be calculated using the formula: Density of alloy = (mass percentage of component 1 * density of component 1) + (mass percentage of component 2 * density of component 2) Let's calculate the density for each alloy: For Alloy Show more…

The karat scale used to describe gold alloys is based on mass percentages. (a) If an alloy is formed that is 50 $\mathrm{mol} \%$ silver and 50 $\mathrm{mol} \%$ 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 $\mathrm{mol} \%$ copper and 50 $\mathrm{mol} \%$ gold, what is the karat number of the alloy? What is the color of this alloy?
The karat scale used to describe gold alloys is based on mass percentages. (a) If an alloy is formed that is $75 \mathrm{~mol} \%$ silver and $25 \mathrm{~mol} \%$ 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 75 mol\% copper and 25 mol\% gold, what is the karat number of the alloy? What is the color of this alloy?
