The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / moleTo convert moles to atoms:atoms B = 2.47 mol B6.02 x 1023 atoms B = 1.49E+24 atoms B1 mol BMultiply by atoms per mole. Moles cancel out.
The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
About 1.2 times ten to the 24th power. This is so much more money than has ever existed that it's almost meaningless. (To give some perspective, there's about 1.2 times ten to the 12th dollars in circulation right now; if you piled all of it up, it would take a trillion such piles to make two moles of dollars.)
6.02 x 1023 is Avogadro's number, to 3 significant digits. A mole of anything is that number of particles (in the case of water, molecules).
The number of atoms cannot be estimated to that degree of accuracy.
2.01x10^22 atoms x 1 mole/6.02x10^23 atoms = 0.0334 moles
The answer is 0,465 moles.
Quite a few! 392 grams phosphorous (1 mole P/30.97 grams) = 12.7 moles phosphorous ===================
There are 4.54 x 10^24 atoms in 7.52 moles of Phosphorus because 1 mole of Phosphorus contains 6.022 x 10^23 atoms. Multiplying this by the number of moles gives the total number of atoms in 7.52 moles.
There are (6.023 \times 10^{23}) atoms in 1 mole of any substance (Avogadro's number). Therefore, there are (1.004 \times 6.023 \times 10^{23} \approx 6.05 \times 10^{23}) atoms in 1.004 moles of bismuth.
There are (~6.022 \times 10^{23}) atoms in one mole of sulfur. Therefore, in 3 moles of sulfur there are (~3 \times 6.022 \times 10^{23} \approx 1.807 \times 10^{24}) atoms of sulfur.
1.51 X 1015 atoms (1 mole/6.022 X 1023) = 2.51 X 10 -9 moles ===============
1,638 moles contain 9,864266723766.10e23 atoms.
To find the number of atoms in a compound, you need to first calculate the number of moles of the compound. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. In this case, for Phosphorous 2 Oxygen 5, you would first calculate the molar mass, find the number of moles from the mass given, and finally convert moles to atoms using Avogadro's number.
20 moles
This is equivalent to 1,4 moles.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
