Calculate number of molecules in 1 ml of `Co_(2)` at NTP.

Explanation

To calculate the number of molecules in 1 mL of CO₂ at Normal Temperature and Pressure (NTP), we can follow these steps:

### Step 1: Convert Volume from mL to Liters
1 mL = 1 × 10⁻³ L

### Step 2: Calculate the Number of Moles
At NTP, 1 mole of gas occupies 22.4 L. Therefore, the number of moles (n) in 1 mL (or 1 × 10⁻³ L) of CO₂ can be calculated using the formula:
\[
