This depends on the mass of the gold sample.
118 Neutrons are in the Element Gold.The number of neutrons can vary for an element, but for gold the stable isotope has 118 neutrons.This is gold-197 (197-Au) and includes virtually all naturally occurring gold on Earth.Synthetic radioisotopes of gold are 195-Au, 196-Au, 198-Au, and 199-Au.All atoms of gold have 79 protons, and neutral atoms have 79 electrons.
Gold (the natural isotope 197Au) contain 79 protons, 118 neutrons and 79 electrons.
The gram atomic mass of Au is 196.967. Therefore, 42.0000 g contains 42.0000/196.92 or 0.213234 gram atoms of gold. The number of atoms is 0.213234 X Avogadro's Number or 1.28412 X 1023 atoms.
The mass of 1 mole of an element is its atomic weight in grams.1 mole of an element is 6.022 x 1023 atoms of that element.Known/Given:1 mol Au = 196.96655g Au (atomic weight in grams)1 mol Au = 6.022 x 1023 atoms Au (Avagadro's number)1000g = 1 kgConvert kilograms to grams.1.500kg Au x (1000g/1kg) = 1500g AuConvert grams to moles.1500gAu x (1mol Au/196.96655g Au) = 7.616mol AuConvert moles to atoms.7.616mol Au x (6.022 x 1023 atoms Au) = 4.586 x 1024 atoms Au
Gold is a metal element. atomic number of it is 79.

5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 1.5 X 1022 atoms of gold ===================
This depends on the mass of the gold sample.
1g AU = 1000mg Au 1 mole Au = 196.96655g Au 1 mole Au = 6.022 X 1023 atoms Au Calculation: 328mg Au x (1g Au /1000g Au) x (1 mole Au/196.97g Au) x (6.022 X 1023 atoms Au/1mole Au) = 1.00 x 1021 atoms Au
1 mole of gold is 196.97 grams. 7.2 mol Au * (196.97 g Au/1 mol Au) = 1418.18 g There are 1418.18 grams in 7.2 moles of gold.
