you take the atomic mass of the atom (or molecule) and you have the mass in grams
Since a single atom is specified, the mass number of the particular isotope that the atom represents needs to be known. The quotient of the mass number and Avogadro's Number will give the approximate mass of the single atom in grams. (For the most accurate answer, the slight difference in mass between a proton and a neutron and the mass of the electrons in the atom will also need to be considered.)

The average mass of a single silicon atom in grams is the ratio 28,085/6,022140857.10e23.
35.5 grams per mole or 5.90*10^-23 for a single atom

Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.
The molar mass of bromine is approximately 79.9 grams/mol. Since one mole of any substance contains Avogadro's number of particles (6.022 x 10^23), the mass of a single bromine atom is approximately 79.9 grams/mol divided by 6.022 x 10^23, which is approximately 1.33 x 10^-22 grams.
Since Argon has a relative atomic mass of 39.95, and mols = grams / RAM, one could calculate 39.95 / (6.02*10^23) = 6.63 * 10^-23 grams [0.00000000000000000000006634g] for a single argon atom, where 6.022 * 10^23 is roughly Avogadro's constant (the count of atoms in a mole). IF my math is correct.
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.
