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
