What is the mass of 5.44 x 10 to the 25 power atoms of silver?

By definition, Avogadro's Number, about 6.022 X 1023, for an element is the number of atoms in one gram Atomic Mass. The gram atomic mass of silver is 107.868. Therefore, the mass of 5.44 X 1025 atoms of silver is [(5.44 X 1025)/(6.022 X 1023)] X 107.868 or 974 grams, to the justified number of significant digits.
