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

The atoms of a substance can be determined by dividing the given mass of the substance by the molar mass. This results to moles of the substance. Then we multiply by the Avogadro's number. In this case, we divide 1 g by 58. 69 g / mol and multiply by 6.022 x10^23 atoms / mole. The answer is 1.03 x10^22 atoms
