Question
Pure gold is usually too soft for jewelry, so it is often alloyed with othermetals. How many gold atoms are in 0.255 -ounce 18 $\mathrm{K}$ gold bracelet?$(18 \mathrm{K}$ gold is 75$\%$ gold by mass.)
Step 1
To do this, we need to know the conversion factor between ounces and grams. 1 ounce is equal to 28.3495 grams. Therefore, we can multiply the mass of the bracelet in ounces by this conversion factor to get the mass in grams. 0.255 ounces * 28.3495 grams/ounce = Show more…

Pure gold is usually too soft for jewelry, so it is often alloyed with other metals. How many gold atoms are in a 0.255-ounce 18 K gold bracelet? (18 K gold is 75% gold by mass.)
For thousands of years, gold has been considered one of Earth's most precious metals. One hundred percent pure gold is 24 -karat gold, which is too soft to be made into jewelry. In the United States, most gold jewelry is 14 -karat gold, approximately 58$\%$ gold. If 18 -karat gold is 75$\%$ gold and 12 -karat gold is 50$\%$ gold, how much of each should be used to make a 14 -karat gold bracelet weighing 300 grams?

F. For thousands of years, gold has been considered one of Earth's most precious metals. One hundred percent pure gold is 24 -karat gold, which is too soft to be made into jewelry. In the United States, most gold jewelry is 14 -karat gold, approximately $58 \%$ gold. If 18 -karat gold is $75 \%$ gold and 12 -karat gold is $50 \%$ gold, how much of each should be used to make a 14 -karat gold bracelet weighing 300 grams?
