The number 174 in platinum refers to mass number or A. This is applicable to atomic nuclei of Pt 174 isotope.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Cobalt is an atomic mass of 58.93 atomic mass units
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Platinum is a metal element. Atomic mass of it is 195.
Platinum has the atomic weight (not mass) 195,084.
Platinum is a meta element. Atomic mass of it is 196.
Platinum is a metal element. Atomic mass of it is 195.08.
Platinum is a metal element. Atomic mass of it is 195.08.
Platinum has an atomic mass of 195.08 & Vanadium has an atomic mass of 50.9415. So platinum is bigger in size.
Platinum is a meta element. Atomic mass of it is 195.
Platinum is a metal element. Atomic mass of it is 195.
Platinum is a metal element. Atomic mass of it is 195.
When measuring mass, you need a unit of measurement, not a dimensionless number. In the case of an atom, you would use atomic mass units. Platinum weighs a lot more than 3.25 atomic mass units. It is a heavy metal.
