Answer:
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
Ring is made of platinum.
This is about density of an unknown element.
We are told there is water in a graduated cylinder up to 10 mL.
This means the volume of water here is 10 mL.
Now, a ring of mass 107 g is put into the water and it rises to a height of 15 mL. This indicates an increase of 5 mL from the original volume.
For the water level to rise by 5 mL after putting the ring inside the water, it means the volume of the ring is 5 mL.
To find what the ring is made of, we have to find it's density from the formula;
Density = Mass/Volume
Plugging in the relevant values, we have;
Density = 107g/5mL
Density = 21.4 g/mL
We need to convert this density to a more standard form of g/cm³.
From conversions;
1 g/mL = 1 g/cm³
Thus; density of ring = 21.4 g/cm³
Looking at the density table of metals attached we can find that the metal with the closest density to 21.4 g/cm³ which is platinum with 21.5 g/cm³.
Ring is made of platinum.
