All the masses of the elements are determined relative to 12C. Since many elements have a number of isotopes, chemists use average atomic mass. On the periodic table the mass of carbon is reported as 12.011 amu.

No single carbon atom has a mass of 12.01 amu, but in a handful of C atoms the average mass of the carbon atoms is 12.01 amu….Element. mass of 1 atom (amu) mass of 100 atoms (amu) H. 1.0079. 100.79. C. 12.01. 1,201. W. 183.9. 18,390.

Gram atomic mass is the mass in grams of one mole of atoms in a mono atomic element. or The atomic mass of an element expressed in grams is called gram atomic mass. For example Nitrogen is 14 grams. The quantity of the element which weighs equal to its gram atomic mass is called One gram atom of that element.

107.8 g

For e.g. Silver has atomic weight or atomic mass of 107.8682 , so its gram atomic mass is 107.8682 gm. It simply means that if you take a sample of 107.8682 gm of silver then it will contain 1 mole or 6.023 X 10^23 atoms of silver .

5 moles

of atoms/Avogadro constant = 12.044 × 1023/6.022 × 1023 = 2 mole Mass of carbon atoms = No. of moles × atomic mass = 2 × 12 = 24 g.

◀️ 24 g. Explanation: Please Check the unit If the final Answer is Wrong.

By definition, a mole of carbon-12 atoms weighs 12 grams. A mole of anything contains of that thing. Dividing we get that the mass of 1 atom of C-12 is grams. So 10 atoms of carbon-12 has 10 times that mass.

atoms in a drop of water = 3 atoms/molecule x 1.67 x 1021 molecules. atoms in a drop of water = 5.01 x 1021 atoms.
