What is the mass of one mole of atoms?

12 atoms x 1.66 x 10-24g x 6.022 x 1023 atoms/ mol= 12 g/mol. So a single carbon atom weighs 12 amu while a mole of carbon atoms weighs 12.01g/mol.

What is the name for the mass of 1 mol of atoms?

Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).

What is the mass of a single atom?

The mass of a single atom of an element [amu] is numerically equal to the mass [g] of 1 mol of that element, regardless of the element. 1 atom of 12 C has a mass of 12 amu 1 mol 12 C has a mass of 12 g.

What is the mass of one mole Na?

And whereas one sodium atom has an approximate mass of 23 u, 1 mol of Na atoms has an approximate mass of 23 grams. One mole of a substance has the same mass in grams that one atom or molecule has in atomic mass units.
