One mole of calcium ions has the same number of representative particles as which of the following? one mole of calcium nuclei one mole of calcium atoms 6.02 x 1023 calcium ions all of these are correct.

One mole is always the same number: 6.02 * 10^ 23.

So, one mole of cars = 6.02 * 10 ^23 cars; one mole of pencils = 6.02 * 10^23 pencils; one mole of atoms = 6.02 * 10^23 atoms; one mole of molecules = 6.02 * 10^23 molecules.

So, all the options are correct: one mole of calcium ions has 6.02 * 10^23 representative particles, such as one mole of calcium nuclei and one of calcium atoms.

Is there any options, for this
