You find a ring with a mass of 107 g. You fill a graduated cylinder up with 10 ml of water and put the ring into the cylinder. The water rises up to the 15 ml mark. What is the ring made of?

Platinum

Step-by-step explanation:

If the water rises by 5 mL then that is the volume of the ring, using this and the mass (107g) we can find the density of the metal using

Density = Mass/Volume

Density = 107g/5mL

Density = 21.4 g/mL

If we look at a density chart on google we can find that the metal with a density of 21.4 g/mL is platinum
