Introduction

In chemistry, understanding the composition and quantity of substances is crucial for various applications. In this article, we will explore how to determine the quantity of carbon tetrafluoride (CF4) present in a given sample. We will use the information provided about the number of fluorine atoms and the number of moles of fluorine to calculate the quantity of CF4.

Understanding the Formula

The formula for carbon tetrafluoride is CF4, indicating that one molecule of CF4 contains one carbon atom and four fluorine atoms. This information is essential for calculating the quantity of CF4 present in the sample.

Calculating the Quantity of CF4

To determine the quantity of CF4 present, we need to use the information provided about the number of fluorine atoms and the number of moles of fluorine. We are given that the sample contains $1.05 \times 10^{24}$ atoms of fluorine and 1.74 moles of F.

Step 1: Calculate the Number of Moles of Fluorine

First, we need to calculate the number of moles of fluorine present in the sample. We can use the formula:

moles = number of atoms / Avogadro's number

where Avogadro's number is $6.022 \times 10^{23}$ atoms/mol.

# Import necessary modules
import math

# Define variables
number_of_atoms = 1.05 * (10**24)
avogadro_number = 6.022 * (10**23)

# Calculate the number of moles of fluorine
moles_of_fluorine = number_of_atoms / avogadro_number

print("The number of moles of fluorine is:", moles_of_fluorine)

Step 2: Calculate the Quantity of CF4

Now that we have the number of moles of fluorine, we can calculate the quantity of CF4 present in the sample. Since the formula for CF4 is CF4, we know that one molecule of CF4 contains one carbon atom and four fluorine atoms. Therefore, the number of moles of CF4 is equal to the number of moles of fluorine divided by 4.

# Calculate the quantity of CF4
quantity_of_cf4 = moles_of_fluorine / 4

print("The quantity of CF4 is:", quantity_of_cf4)

Conclusion

In this article, we have explored how to determine the quantity of carbon tetrafluoride (CF4) present in a given sample. We used the information provided about the number of fluorine atoms and the number of moles of fluorine to calculate the quantity of CF4. By following the steps outlined in this article, you can determine the quantity of CF4 present in a sample.
