How many atoms of gold are in 0.02 g of Au?
6.14x1019 atoms Au
How many gold atoms would there be in 328 milligrams of gold?
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
How many atoms are in 3.50 g of gold?
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.
How many gold atoms would there be in 0.0148 milligrams of gold?

How many atoms of gold are in a necklace that weighs 12.7g?
12.7 g gold (1 mole Au/197.0 grams)(6.022 X 10^23/1 mole Au) = 3.88 X 10^22 atoms of gold
How many atoms of gold are in 0.02 g of Au?
6.14x1019 atoms Au
How many atoms are there in 42.0000 g of Au?
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.
How many gold atoms does Au contain?
This depends on the mass of the gold sample.

How many neutrons in gold?
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.
5.6 moles of gold contain how many atoms?
5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 1.5 X 1022 atoms of gold ===================
What is the mass of 3.34 moll of gold atoms?
1mole Au atoms = 196.97g Au (atomic weight in grams) 3.34mol Au x 196.97g Au/1mol Au = 658g Au
How many atoms of gold were recovered in 197kg of gold?
Quite a few! 197 kilograms gold (1000 grams/1 kg)(1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 6.02 X 1026 atoms of gold ------------------------------------
Which would contain more electrons a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
