Answer 2

18 Carat gold jewelry is (B) 18 parts are made up of gold and 6 parts are copper.

Explanation:

• Jewelry made of 18-karat gold strikes a nice mix between durability and purity.
• Although yellow gold is still the most popular color, gold is now available in a wide range of colors. Alloying, which involves adding other metals with pure 24-carat gold, improves the endurance of malleable gold while also changing its color. Gold is measured in troy ounces (1 troy ounce = 31.1034768 grams), although its purity is expressed as 'carats.'

• When a piece of jewelry has 18 karats, it simply implies that 18 of the 24 pieces of the piece are gold, and 6 are made up of copper. In percentage terms, 18 karats correspond to a gold content of 75%. (18 divided by 24). Metals like zinc, copper, nickel, and others typically make up the remaining 25%. The extra metals in 18K gold make the alloy more durable and tougher than pure gold (24K), which is too soft for jewelry.
