Question

A jeweler is creating a unique ring, and melts 16 g of silver in a sealed environment. Once the silver hardens, this jeweler sculpts the ring, reheats it, and adds 2 g of nickel. He delivers the ring to his client, who does not like it and asks him to remake it. The jeweler reheats the ring and tries again. What is the total mass of the ring at this point?

A) 14g
B) 16g
C) 18g
D) 20g

Answer 1

The total mass of the ring after remaking it is the combined mass of silver and nickel, which is 18 grams.

Step-by-step explanation:

The total mass of the ring after the jeweler reheats it and tries again is the sum of the initial mass of silver and the added mass of nickel. The jeweler originally melts 16 g of silver, and later adds 2 g of nickel. The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. Hence, the total mass of the ring after remaking it is the combined mass of silver and nickel.

The total mass of the ring is 16 g silver + 2 g nickel = 18 g.

The correct answer is: C) 18g.
