A mole is Avagadro's number (6.0221415 × 10^23) atoms of any particular element. Therefore a mole of hydrogen contains 6.0221415 x 10^23 atoms of hydrogen.
The number on the periodic table representing the mass in grams of one mole of atoms in an element is called the molar mass, which is expressed in grams per mole. It is numerically equal to the atomic mass in atomic mass units (amu) of the element.
The atomic mass of an element listed in the periodic table is the weighted average mass of all the isotopes of that element, taking into account their natural abundance. It is expressed in atomic mass units (amu) or grams per mole (g/mol).
In one mole of Uranium there are 238.02891g of Uranium. This number comes from its atomic weight on the Periodic Table. The mass of one mole of an element is its atomic weight in grams.
1) Get the chemical formula to determine the number of each type of atom present in the compound. 2) Multiply the atomic weight (get it from the periodic table) of each element by the number of atoms of that element present your specific compound 3) Do the Sum in unit grams/mole NaCl (1x23 grams/mole Na) + (1x 35.5 grams/mole Cl) = 58.5 grams/mole NaCl
The molar mass of an element is the mass of one mole of atoms of that element, typically expressed in grams per mole (g/mol). It is numerically equivalent to the atomic mass of the element, which is found on the periodic table, but is specifically expressed in terms of mass per mole. For example, the molar mass of carbon is approximately 12.01 g/mol.

one mole of atoms of the element
Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the periodic table.
The atomic mass of an element listed in the periodic table is the weighted average mass of all the isotopes of that element, taking into account their natural abundance. It is expressed in atomic mass units (amu) or grams per mole (g/mol).
The weight of one mole of an element is the element's atomic mass. So Carbon for example has an atomic mass of 12. If you had one mole of Carbon you would have 12 grams of Carbon.
In one mole of Uranium there are 238.02891g of Uranium. This number comes from its atomic weight on the Periodic Table. The mass of one mole of an element is its atomic weight in grams.
The weight of a mole depends on the substance you are measuring. The formula is as follows 6.022e23 (Avogadro's number) multiplied by the atomic weight of the element you wish to measure. You can find the atomic weight for any element on the periodic table of elements.

Simple: the atomic weight expressed in grams. Example for dysprosium - 162,500 grams.
one mole of He
Yes. An element on the periodic table. 6.022 X 10^23 atoms of aluminum have a mass of 26.98 grams/mole. ( the mole value being 6.022 X 10^23; no units )
