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
