Problem Silver (Ag) is used in jewelry and tableware but no longer in U.S. coins. How many grams of Ag are in 0.0342 mol of Ag?Plan We know the amount of Ag (0.0342 mol) and have to find the mass (g). To convert units of moles of Ag to grams of Ag, we multiply by the molar mass of Ag, which we find in the periodic table (see the road map).

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
