How many kilograms of chlorine are in 22 kg of each of the following chlorofluorocarbons CFCs?
1.CF2Cl2
2.CFCl3
3.C2F3Cl3
4.CF3Cl
How many kilograms of chlorine are in 22 kg of CFCl3?
1. CF2Cl2: Well, CF2Cl2 contains two atoms of chlorine, so you'd have a total of 44 kg of chlorine. That's enough chlorine to start a swimming pool party!
2. CFCl3: CFCl3 has three atoms of chlorine, so you'd have 66 kg of chlorine. That's enough chlorine to turn your neighborhood into a giant bubble bath!
3. C2F3Cl3: This compound has three atoms of chlorine, so you'd have 66 kg of chlorine. That's enough chlorine to give even the most stubborn stains a good scrub!
4. CF3Cl: CF3Cl has one atom of chlorine, so you'd have 22 kg of chlorine. That's enough chlorine to make any chemist green with envy!
Remember, though, that these chemicals are not only hilarious but also potentially harmful to the environment, so let's try to use them responsibly!
To determine the number of kilograms of chlorine in each of the chlorofluorocarbons (CFCs), you need to know the molecular formulas of the compounds. From the molecular formulas, you can calculate the molar mass of each compound and determine the percentage of chlorine present.
Let's calculate the number of kilograms of chlorine for each CFC:
1. CF2Cl2 (Dichlorodifluoromethane)
Molecular Formula: CF2Cl2
Molar Mass of Carbon (C) = 12.01 g/mol
Molar Mass of Fluorine (F) = 18.99 g/mol
Molar Mass of Chlorine (Cl) = 35.45 g/mol
Molar Mass of CF2Cl2 = (12.01 * 1) + (18.99 * 2) + (35.45 * 2) = 121.91 g/mol
Percentage of Chlorine in CF2Cl2:
Chlorine's molar mass / Molar mass of CF2Cl2 = (35.45 g/mol / 121.91 g/mol) * 100 = 29.04%
To find the kilograms of chlorine in 22 kg of CF2Cl2:
Kilograms of chlorine = 22 kg * (29.04 / 100) = 6.39 kg
Therefore, there are approximately 6.39 kilograms of chlorine in 22 kg of CF2Cl2.
You can follow a similar process to calculate the kilograms of chlorine for the remaining CFCs:
2. CFCl3 (Trichlorofluoromethane):
Molar Mass of CFCl3 = (12.01 * 1) + (18.99 * 1) + (35.45 * 3) = 137.33 g/mol
Percentage of Chlorine in CFCl3:
Chlorine's molar mass / Molar mass of CFCl3 = (35.45 g/mol / 137.33 g/mol) * 100 = 25.82%
Kilograms of chlorine in 22 kg of CFCl3 = 22 kg * (25.82 / 100) = 5.69 kg
3. C2F3Cl3 (Trichlorotrifluoroethane):
Molar Mass of C2F3Cl3 = (12.01 * 2) + (18.99 * 3) + (35.45 * 3) = 187.35 g/mol
Percentage of Chlorine in C2F3Cl3:
Chlorine's molar mass / Molar mass of C2F3Cl3 = (35.45 g/mol / 187.35 g/mol) * 100 = 18.93%
Kilograms of chlorine in 22 kg of C2F3Cl3 = 22 kg * (18.93 / 100) = 4.17 kg
4. CF3Cl (Trifluorochloromethane):
Molar Mass of CF3Cl = (12.01 * 1) + (18.99 * 3) + (35.45 * 1) = 104.45 g/mol
Percentage of Chlorine in CF3Cl:
Chlorine's molar mass / Molar mass of CF3Cl = (35.45 g/mol / 104.45 g/mol) * 100 = 33.98%
Kilograms of chlorine in 22 kg of CF3Cl = 22 kg * (33.98 / 100) = 7.48 kg
Therefore, in 22 kg of each of the mentioned CFCs, you would have:
1. CF2Cl2: 6.39 kg of chlorine
2. CFCl3: 5.69 kg of chlorine
3. C2F3Cl3: 4.17 kg of chlorine
4. CF3Cl: 7.48 kg of chlorine
Convert 22,000 g to moles. moles = grams/molar mass
moles chlorine (Cl2) = 1 per mole CF2Cl2.
g Cl2 = moles Cl2 x molar mass Cl2.
