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)
A mole of silver contains approximately 6.022 x 10^23 atoms.
There are 6.022x1023 atoms in a mole. You multiply 6.022x1023 by 8.68, which equals 52.20796x1023 atoms
2.3 X 1024 atoms / 6.022 X 1023 atoms/mole X 107.87 gm/mole of silver = 412 grams
A mole of any substance contains the same number of atoms, which is approximately 6.022 x 10^23. Therefore, a mole of silver atoms and a mole of gold atoms would both contain the same number of atoms.
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
There are 6.022 x 10^23 atoms in 1 mole of silver (Ag) as per Avogadro's number.
0.050 moles silver (6.022 X 1023/1 mole Ag) = 3.01 X 1022 atoms of silver --------------------------------------
1 mole of silver contains Avogadro's number of silver atoms, while 1 mole of gold contains Avogadro's number of gold atoms. The molar mass of silver and gold can be used to determine the mass of each element in 1 mole. Both contain the same number of atoms per mole due to Avogadro's number.
There are 4 O atoms per molecule Ag3PO4 .In 0.02 mole Ag3PO4 are0.02(mole) * 6.022*10+23(molecules/mole) * 4(atolms/molecule) = 4.8*10+22 atoms Oxygen
To find the number of atoms of silver in 10.8g, you need to first calculate the number of moles of silver using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the moles of silver to number of atoms.
To calculate the number of silver atoms in 3.76g of silver, you need to use Avogadro's number and the molar mass of silver. The molar mass of silver is 107.87 g/mol. First, calculate the number of moles in 3.76g of silver. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of silver atoms in that many 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.
