By definition, in Chemistry, a "mole" refers to 6.022 x 10^23 atoms of a specific element. That number was determined by Avogadro and it turns out that a mole of any element weighs (in grams) the atomic mass of the element.
For example, oxygen has an atomic mass of 16, so a mole of oxygen weighs 16 grams.
Thus, for your problem, 4.25 X 10^25 divided by 6.022 X 10^23
= ???

Divide by 6.022 x 10^23. A mole of a substance includes 6.022 x 10^23 debris of that substance; this type is common as Avogadro's type. Your pattern includes below one mole.
