A ring weighing 9.45 g is placed in a graduated cylinder containing 25.3 mL of water. After the ring is added to the cylinder the water rises to 27.4 mL. What metal is the ring made out of? Assume the ring is a single metal.

Titanium metal.

Explanation:

Mass of ring = 9.45 g

Initial Volume = 25.3 mL

Final Volume = 27.4 mL

Volume of ring = 27.4 - 25.3 = 2.1mL

Density = Mass / Volume

Density = 9.45 / 2.1

Density = 4.5g/ml

Since, the ring is a single metal, we look for the metal that has a density of 4.5g/ml. This metal is the Titanium metal.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
