You just bought a gold chain necklace in a flee market and paid a good chunk of money for it. After showing the necklace to your physicist friend, she was a little suspicious and decided to check in her lab whether the metal was really gold. The weight of the necklace in air was 0.0784 N (8g) and in water was 0.049 N (5g). Then she calculated the density of the necklace and compared with the density of gold (19.32 x 103 kg/m3). Was it gold or not

The answer is 2.67x10^3 kg/m3. Need help solving it.
