Answer:

3Cu + $8HNO_{3}$ → 3 $Cu(NO_{3} )_{2}$ +4 $H_{2}O$ + 2NO

Explanation:

Considering the number of each atom in both reactants, it must be equal to the number of each atom in the product. Thus, the number of copper atom, hydrogen atom, nitrogen atom and oxygen atom must be equal on both sides of the equation.

Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<u>Stoichiometry</u>

Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

4.93 × 10²³ atoms Ag

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

Set up: $\displaystyle 4.93 \cdot 10^{23} \ atoms \ Ag(\frac{1 \ mol \ Ag}{6.022 \cdot 10^{23} \ atoms \ Ag})$
Divide: $\displaystyle 0.818665 \ mol \ Ag$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

0.818665 mol Ag ≈ 0.819 mol Ag
