Problem: (a) How many grams of silver, Ag, are in 0.0342 mol Ag? (b) How many atoms of Ag are in 0.0342 mol Ag?
7
Plan: (a) To convert moles Ag to grams Ag, use the molar mass of Ag from the periodic table. (b) To convert moles to number of atoms, use Avogadroís number.
Solution: (a) Converting from moles of Ag to mass:
(b) Converting from moles of Ag to number of atoms:
= 2.06 x 1022 atoms Ag
