Which of the following statements about moles is correct? a mole of cu atoms has the same number of atoms as a mole of he atoms. a mole is 6.02 x 1024 there are more atoms in a mole of carbon than in a mole of helium. a mole is 6.2 x 1022

A mole of Cu atoms has the same number of atoms as a mole of He atoms.

Explanation: Mole is a bigger unit that counts  . For example, one mole of electrons equals to electrons.

One mole of atoms equals to . First choice is correct as we have a mole of Cu and He(equal moles of Cu and He) and so the number of atoms will also be equal.

Second and fourth choices are not correct as a mole neither equals to nor equals to 6.022*10^2^2[/tex] .

Third choice is also not correct as if we have equal moles of carbon and He then number of atoms will be same.

So, the only and only correct choice is the first one. A mole of Cu atoms has the same number of atoms as a mole of He atoms.

girl imma just put my comment here because i need a couple point okurrttt
