To find the number of moles of copper, we first need to calculate the total mass of copper in the sample. Copper has an atomic mass of 63.55 g/mol. The total mass of the sample is 1.20 g x 1024 atoms = 1228.8 g. Next, we convert this mass to moles by dividing by the atomic mass of copper: 1228.8 g / 63.55 g/mol = 19.36 moles of copper.
To find the number of moles, divide the number of atoms by Avogadro's number, which is approximately 6.022 x 10^23. In this case, 2.4081024 atoms of carbon divided by Avogadro's number equals approximately 4 x 10^-3 moles of carbon.
To convert atoms to moles, you divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, 1.53 x 10^24 atoms of carbon divided by Avogadro's number is equal to 2.54 moles of carbon.
To determine the number of moles of N2O3 containing 2.55 x 10^24 oxygen atoms, we first calculate the molar mass of N2O3, which is 76.01 g/mol. Next, we find the number of moles of oxygen atoms in 2.55 x 10^24 atoms by dividing the given number by Avogadro's number (6.022 x 10^23 atoms/mol). This gives us approximately 4.24 moles of oxygen atoms. Since each mole of N2O3 contains 3 moles of oxygen atoms, the number of moles of N2O3 containing 2.55 x 10^24 oxygen atoms is 4.24 moles / 3 = 1.41 moles.
(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles

1,67.1024 argon atoms is equal to 2,773 moles.
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms of copper ====================
The answer is 15,2 moles.
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
Whatever be the substance the one gram mole of that substance would have 6.023 x 1023 atoms or molecules or ions in it. Hence to get the mole just divide the number given by 6.023 x 1023
2.26*1024
To convert atoms to moles, you divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, 1.53 x 10^24 atoms of carbon divided by Avogadro's number is equal to 2.54 moles of carbon.
The number of moles is 0,528.
If it is 1.54 moles of Br atoms then the answer is 9.274 X 1023 atoms.If it is 1.54 moles of Br2 molecules then the answer is 1.855 X 1024 atoms.
