1 mol = 6.02 x 10^23
2.88 x 1023 atoms = 2946.24 atoms = (2946.24) / (6.023 x 10^23) moles
= 4.89 x 10^-21moles
Or if you meant=> 2.88 x 10^23 atoms = (2.88/6.02) moles = 0.478 moles (3 s.f)
To find the mass of 3.34 moles of gold atoms, you need to multiply the number of moles by the molar mass of gold. The molar mass of gold is 196.97 g/mol. Therefore, the mass of 3.34 moles of gold atoms is 3.34 moles * 196.97 g/mol = 658.5 grams.
n(Au)= 1.5g/M(Au)= 1.5/196.97 = 0.00761537mol n(Au) = No(Atoms)/N(a)therefore N(Atoms)=n(Au) x N(a)N(atoms) = 0.00761537mol x 6.02x10^23mol*-1N(atoms) approximatly equals 4.6x10^21 atoms
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.

To calculate the number of atoms in 0.02 g of gold (Au), you first need to determine the number of moles of gold in 0.02 g using the molar mass of gold (196.97 g/mol). Then, you use Avogadro's number (6.022 x 10^23 mol^-1) to convert moles to atoms. The calculation would be 0.02 g Au / 196.97 g/mol Au × 6.022 x 10^23 atoms/mol.

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
For this you don't need to have the atomic mass. Take the number of atoms and divide it by Avogadro's constant, 6.02 × 1023. Multiply by one mole for units to cancel.20.00 atoms Au / (6.02 × 1023 atoms) = 3.32 × 10-23 moles of Au

To calculate the number of atoms in 0.02 g of gold (Au), you first need to determine the number of moles of gold in 0.02 g using the molar mass of gold (196.97 g/mol). Then, you use Avogadro's number (6.022 x 10^23 mol^-1) to convert moles to atoms. The calculation would be 0.02 g Au / 196.97 g/mol Au × 6.022 x 10^23 atoms/mol.
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.
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.
5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 1.5 X 1022 atoms of gold ===================
To find the number of moles in 2.61 x 10^24 atoms of gold, you first need to divide the number of atoms by Avogadro's number (6.022 x 10^23). So, 2.61 x 10^24 atoms of gold / 6.022 x 10^23 atoms/mol = approximately 4.33 moles of gold.
To find the number of gold atoms, you first need to calculate the number of moles of gold using the molar mass of gold (197 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. First, convert the weight of the necklace (12.7g) to moles using the molar mass of gold. This will give you the total number of atoms in the necklace.
