Answer:
3.42 × 10²³ atoms CuCl
General Formulas and Concepts:
- Avagadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
- Dimensional Analysis
Explanation:
Step 1: Define
3.42E23 molecules CuCl
3.42 × 10²³ molecules CuCl
Step 2: Convert (DA)
[tex]3.42 \cdot 10^{23} \ molecules \ CuCl(\frac{6.02 \cdot 10^{23} \ atoms \ CuCl}{6.02 \cdot 10^{23} \ molecules CuCl} )[/tex] = 3.42 × 10²³ atoms CuCl
- molecules CuCl and molecules CuCl cancel out
- left with atoms CuCl as final unit
Step 3: Check
We have 3 sig figs. Follow sig fig rules.
Since our answer already has the correct number of sig figs, there is no need to change it.
