How many kilograms of chlorine are in 26 kg of C2F3CL3?
What is the percent Cl in C2F3Cl3?
%Cl = (3*atomic mass Cl/molar mass C2F3Cl3)*100 = ??
Then (%Cl/100) x 26 kg = ??
56.8% of Cl
To calculate the number of kilograms of chlorine in 26 kg of C2F3Cl3, we need to find the molar mass of C2F3Cl3 and the molar mass of chlorine.
The molar mass of C2F3Cl3 can be calculated by adding up the atomic masses of carbon (C), fluorine (F), and chlorine (Cl) in the compound.
Carbon (C) has an atomic mass of 12.01 g/mol.
Fluorine (F) has an atomic mass of 19.00 g/mol.
Chlorine (Cl) has an atomic mass of 35.45 g/mol.
Molar mass of C2F3Cl3 = 2 * 12.01 + 3 * 19.00 + 3 * 35.45
= 24.02 + 57.00 + 106.35
= 187.37 g/mol
Next, we need to calculate the molar mass of chlorine.
The molar mass of chlorine (Cl) is 35.45 g/mol.
Now, we can calculate the amount of chlorine in 26 kg of C2F3Cl3 using the ratio of molar masses.
Number of moles of C2F3Cl3 = mass / molar mass
= 26000 g / 187.37 g/mol
= 138.68 mol
Number of moles of chlorine = Number of moles of C2F3Cl3 * (3 moles of Cl / 1 mole of C2F3Cl3)
= 138.68 mol * (3 mol / 1 mol)
= 416.04 mol
Mass of chlorine = number of moles of chlorine * molar mass of chlorine
= 416.04 mol * 35.45 g/mol
= 14756.82 g
= 14.76 kg
Therefore, there are approximately 14.76 kilograms of chlorine in 26 kg of C2F3Cl3.
To find the number of kilograms of chlorine in 26 kg of C2F3CL3, we need to determine the molecular formula and calculate the molar mass of C2F3CL3.
The molecular formula of C2F3CL3 is carbon tetrafluoride trichloride. To calculate the molar mass, we need to add up the atomic masses of all the elements in the compound.
The atomic masses (in atomic mass units) of carbon (C), fluorine (F), and chlorine (Cl) can be obtained from the periodic table. The values are approximately:
C: 12.01 u
F: 18.99 u
Cl: 35.45 u
For carbon tetrafluoride trichloride (C2F3CL3), we have:
2 atoms of carbon: 2 * 12.01 u = 24.02 u
3 atoms of fluorine: 3 * 18.99 u = 56.97 u
3 atoms of chlorine: 3 * 35.45 u = 106.35 u
Now, sum up the individual atomic masses to get the molar mass:
Molar mass of C2F3CL3 = 24.02 u + 56.97 u + 106.35 u = 187.34 u
Now, let's calculate the number of moles of C2F3CL3 in 26 kg using the molar mass.
Number of moles = Mass / Molar mass
Mass of C2F3CL3 = 26 kg
Molar mass of C2F3CL3 = 187.34 g/mol = 0.18734 kg/mol
Number of moles of C2F3CL3 = 26 kg / 0.18734 kg/mol ≈ 138.70 mol
Since the compound C2F3CL3 has 3 atoms of chlorine per molecule, we can multiply the number of moles by the ratio of chlorine atoms to C2F3CL3 molecules to obtain the number of moles of chlorine.
Number of moles of chlorine = Number of moles of C2F3CL3 * (3 moles of Cl / 1 mole of C2F3CL3)
Number of moles of chlorine = 138.70 mol * 3/1 = 416.10 mol
Finally, convert the moles of chlorine to kilograms:
Mass of chlorine = Number of moles of chlorine * Molar mass of chlorine
Molar mass of chlorine = 35.45 g/mol = 0.03545 kg/mol
Mass of chlorine = 416.10 mol * 0.03545 kg/mol ≈ 14.74 kg
Therefore, there are approximately 14.74 kilograms of chlorine in 26 kg of C2F3CL3.
