When isotopes are considered, they have the same atomic number but differed mass numbers.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
The atomic mass is grams/mole So when you have e.g. 12 grams of carbon which has atomic mass = 12, you have one mole. ( Avogadro's number is one mole: 6.02×10²³ )
The atomic mass, in grams, is the mass of one mole of atoms.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
The atomic mass of ekasilicon is approximately 118.71 grams per mole.

One mole of gold has a greater mass than one mole of silver because gold has a higher atomic mass compared to silver. The atomic mass of gold is around 197 grams per mole, whereas the atomic mass of silver is around 108 grams per mole.

The mole is the atomic weight expressed in grams.

By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Nitrogen's atomic mass is 14.007 grams.
The atomic mass for Ge (germanium) is approximately 72.63 grams per mole.
The atomic mass of the element in atomic mass units
The atomic mass of Rhenium (Re) is approximately 186.21 grams per mole.
The atomic mass of osmium (Os) is 190.23 grams per mole.
