I want to convert atoms to moles. My friend tells my to multiply the number of atoms by 6.02 x 102. Is my friend

correct?

To covert atoms to moles, you need to divide by Avogadro's number.

Explanation:

Avogadro's number is = 6.0221409e^23, so your friend is close, but it is not to the power of 2, rather 23, and you need to divide, nut multiply.
