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 gold atoms would there be in 0.0148 milligrams of gold?
1 mole of atoms of an element = 6.022 x 1023 atoms.1 mole of an element = atomic weight in grams.1 g = 1000mg1 mole Au atoms = 6.022 x 1023 atoms1 mole Au = 196.96655g AuConvert mg Au to g Au.0.0148mg Au x (1g/1000mg) = 0.0000148g AuConvert mass Au to moles Au.0.0000148g x (1mole Au/196.96655g Au) = 0.0000000751 mole AuConvert moles Au to atoms Au.0.0000000751 mole Au x (6.022 x 1023 atoms Au/1mole Au) = 4.52 x 1016 atoms Au
The number of Au atoms in 1.5g of Au is?
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
Au contains how many gold atoms?
This depends on the mass of the gold sample.
Which would have a higher mass a mole of K atoms or a mole of Au atoms?
A mole of Au atoms would have a higher mass compared to a mole of K atoms because gold (Au) atoms have a larger atomic mass than potassium (K) atoms. The molar mass of a substance is determined by adding the atomic masses of the individual atoms in the mole.

A mole of Au atoms would have a higher mass compared to a mole of K atoms because gold (Au) atoms have a larger atomic mass than potassium (K) atoms. The molar mass of a substance is determined by adding the atomic masses of the individual atoms in the mole.
How many moles make up 20.00 atoms of 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
How many atoms of gold are in 0.02 g 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.
How many atoms are in 1.500 kilograms of gold?

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.
