Question

How many atoms of Chlorine are in 1.00 mol of Chlorine gas?

6.022 x 10∧23
3.01 x 10∧23
6.022 x 10∧24

Answer 1

6.02 × 10²³ atoms Cl₂

Step-by-step explanation:

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

Step 1: Define

1.00 mol Cl₂ (g)

Step 2: Use Dimensional Analysis

`1.00 \hspace{3} mol \hspace{3} Cl_2(\frac{6.02(10)^23 \hspace{3} atoms \hspace{3} Cl_2}{1 \hspace{3} mol \hspace{3} Cl_2} )` = 6.02 × 10²³ atoms Cl₂
