Platinum is a metal. It is a dense, malleable, and ductile metal with a silvery-white color.
Mo is a metal. It belongs to d-block series.
The mass number of an element is the total number of protons and neutrons in its nucleus. Gallium-72 has 31 protons (the atomic number of Gallium) and 41 neutrons, giving it a mass number of 72.
The resulting mass is the same as the original mass, as the total mass during oxidation remains constant due to the conservation of mass principle.
Gallium is a metal. It is a soft, silvery metal that melts just above room temperature.
Mass
The metal block's density is about 13.636 g/cm3
The metal block will displace a volume of water equal to its own volume. By measuring the volume of water displaced, you can then determine the mass of the metal block - as long as you know the density of water (1 gram per cubic centimeter).
They you are the proud owner of a block of metal with a volume of 56 cubic centimetres and a mass of 153 grams. Enjoy!
Just divide the mass by the volume.
Density = Mass/Volume = 13.6 g/cm3
5g/cm3
Different metals have different volumes for the same mass.
If the metal block undergoes oxidation and forms rust on its surface, the mass will increase due to the addition of oxygen and possibly other elements from the environment. Alternatively, if the metal block absorbs moisture from the atmosphere or undergoes a chemical reaction that results in the incorporation of additional atoms into its structure, the mass may also increase.
n. # A mass of metal, such as a bar or block, that is cast in a standard shape for convenient storage or shipment. # A casting mold for metal.
