Cu and He both are separate elements . The no. of atoms differs in different cases.
For example:- if you take 1 mole of both of these you will have equal no. of atoms
but if you take same mass of both, then He will have larger no. of atoms due to
smaller molecular mass.
The number of particals (molecules, atoms, ions etc.) in one mole of ANY substance is the same: 6.022*1023 (Avogadro's number)
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
One part of one mole of anything (eg. atoms in a mole atoms) is 1 / (6*10+23) = 1.6*10-24
Avogadro's number is the number of "elementary entities" (usually atoms or molecules) in one mole. It is 6.0221415 × 1023
One mole of beryllium contains the same number of atoms as one mole of magnesium, which is Avogadro's number, approximately (6.022 \times 10^{23}) atoms. This is true regardless of the element, as one mole of any substance always contains this fixed number of entities. Therefore, if you have one mole of beryllium and one mole of magnesium, both will contain the same number of atoms.
No, the moles of an atom and the moles of a molecule are not the same. A mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. In the case of an atom, this corresponds to one mole of atoms. In the case of a molecule, this corresponds to one mole of molecules.
For the same reason that one dozen pencils has a smaller mass than one dozen bricks. Each atom of carbon weighs less than each atom of sulfur, and a mole of each has the same number of atoms, so a mole S will weigh more than a mole C.
The total number of molecules is equal.

the first inoization energy is 2372.3 kJ mol-1 there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.
Each molecule of methane contains one carbon atom, as shown by the formula for methane, CH4. Therefore, the number of carbon atoms in one mole of methane is the same as Avogadro's Number, about 6.022 X 1023.
Number of nitrogen atoms in 1 mole nitrogen dioxide? Nitrogen dioxide has 1 N atom and 2 O atoms. One mole of nitrogen dioxide has 1 mole of N atoms
Trick question. They are all the same. One mole is a unit of measurement. A mole of feathers and a mole of bowling balls will be the same amount: one mole.
