Divide 1.8*10^20 (unit: number) particles by 6.02*10^23 (unit: number per mole), Avogadro's number) and you'll get
3.0*10^(-4) moles of those particles
(In your case particles are atoms, but this is also valid for ANY kind of particles)
1 mole of silver contains 6.022 X 10^23 atoms 62 moles of silver contains 3.73 X 10^25 atoms of silver
The answer is: Number of Avogadro x 5 = 30,11070645.1023 atoms.
5.42 X 10^24 atoms silver ( 1mole Ag/6.022 X 10^23) = 9.00 moles of silver
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
1 mole of silver contains 6.022 X 10^23 atoms 62 moles of silver contains 3.73 X 10^25 atoms of silver
To calculate the number of moles, you divide the number of atoms by Avogadro's number (6.022 x 10^23). So for 1.8 x 10^25 atoms of silver, the number of moles would be 30 moles.
There are 2.26 x 10^24 silver atoms in 3.75 moles of silver. This is calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mole) by the number of moles.
To find the number of moles of silver in the ring, you need to divide the number of silver atoms by Avogadro's number (6.022 x 10^23 atoms/mol). Number of moles of silver = 1.1 x 10^22 Ag atoms / 6.022 x 10^23 atoms/mol Calculating this gives approximately 0.018 moles of silver in the ring.
2.50 moles silver (6.022 X 1023/1 mole Ag) = 1.51 X 1024 atoms of silver ==================
The answer is: Number of Avogadro x 5 = 30,11070645.1023 atoms.
Quite a few moles of silver if you mean, 4.59 X 10^25 atoms of silver. 4.59 X 10^25 atoms silver (1 mole Ag/6.022 X 10^23) = 76.2 moles of silver ----------------------------
A silver sample with the same mass as the Earth (5.972 × 10^24 kg) would contain about 1.96 × 10^50 atoms of silver. This amount of silver corresponds to approximately 3.25 × 10^25 moles.
To find the number of silver atoms in 4.55 moles of AgNO3, first calculate the molar mass of AgNO3 which is 169.87 g/mol. Then set up a ratio using Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. The calculation would be 4.55 moles x (6.022 x 10^23 atoms/mol) = 2.74 x 10^24 silver atoms in 4.55 moles of AgNO3.
5.42 X 10^24 atoms silver ( 1mole Ag/6.022 X 10^23) = 9.00 moles of silver
The answer is 6,31 moles Ag.
The answer is approx. 1,5.10e23 atoms of silver.
