For this you need the atomic mass of Pt. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.3.08 moles Pt × (195.1 grams) = 601 grams Pt
An isotope of platinum: Pt-198 has an atomic mass of 197.97 a.m.u.
platinum Pt Atomic number 78 Standard atomic weight: 195.084 Density (room temperature) 21.45 g·cm−3
The atomic weight of platinum is: 195.084
The atomic mass unit is used to express the measure of the atomic mass.

The number 174 in platinum refers to mass number or A. This is applicable to atomic nuclei of Pt 174 isotope.
The atomic weight of platinum is: 195.084
Pt
Pt-Platinum Atomic number=78
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The atomic mass unit is used to express the measure of the atomic mass.
Atomic no.=no. of protons Atomic Mass=no. of protons+no. of neutrons Hence, atomic mass is greater
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
