Stoichiometry

Using Dimensional Analysis

<h3>Explanation:</h3>

Step 1: Define

0.55 mol Cu(NO₃)₂

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[DA] Set up: $\displaystyle 0.55 \ mol \ Cu(NO_3)_2(\frac{6.022 \cdot 10^{23} \ molecules \ Cu(NO_3)_2}{1 \ mol \ Cu(NO_3)_2})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 3.3121 \cdot 10^{23} \ molecules \ Cu(NO_3)_2$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

3.3121 × 10²³ molecules Cu(NO₃)₂ ≈ 3.3 × 10²³ molecules Cu(NO₃)₂

How does a balanced chemical equation verify the law of conservation of matter?

$\color {pink}\boxed{\colorbox{white} {✦Answer✦}}$

According to the Law conservation of matter

Mass can neither be created nor destroyed in a chemical reaction. That is, the total mass of the elements present in the products of a chemical reaction has to be equal to the total mass of the elements present in the reactants. In other words, the number of atoms of each element remains the same, before and after a chemical reaction. Hence, we need to balance the skeletal chemical equation.
