There are 3.20x10^22 atoms of silver in your ring. How many grams of silver is this?

The answer to your question is 5.74 g of Silver

Explanation:

Data

number of atoms = 3.20 x 10²²

mass of silver = ?

Process

The atomic number of an element is equal to Avogadro's number (6.023 x 10²³).

1.- Look for the atomic number of Silver

Atomic number = 108 g

2.- Use proportions to calculate the grams of silver

                     108 g of Silver 6.023 x 10²³ atoms

                        x                     3.20 x 10²² atoms

                                 x = (3.20 x 10²² x 108) / 6.023 x 10²³

                                 x = 3.456 x 10²⁴/ 6.023 x 10²³

                                 x = 5.74 g of Silver

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
