Question

How many atoms of nickel can be found in a 1.00 g sample?

Answer 1

You#ll have to use Avogadro's number - 6.022e23. This is relevant because this is the number of atoms in one mole of the element. Nickel has an atomic weight of 58.7, so 1g is 1 over 58.7 moles. From this you should get the answer - if you want to do the calcs I can check back later. Regards,
