how much carbon is in 365 grams of dicarbon tetrachloride?
Is that C2Cl4? I have not heard of dicarbon tetrachloride.
Total C = 2 x 12.01 = 24.02
Total mass C2Cl4 = (2*C + 4*Cl) = 165.83 but confirm that.
mass fraction C in C2Cl4 = 24.02/165.83 = ??
Then mass fraction x 356 = g C
I ended up with 158.4 but I don't kno if its right
but at first I ended up with 52.8
Neither answer is correct. You need to learn how to use your calculator.
356 x (24.02/165.83) = ??
yeah I kno that's not it but I did something different
365/165.83 = 2.20
c2=24.02
24.02x2.20= 52.84
and I meant that's what I got before you answered my question
sorry I should have been more clear
and for the equation you gave me I got 52.86 so its practically the same
24.02/165.83 = .1448471
.1448471 x 365 = 52.87
OK. I see the problem You are using 365 (the original problem) and I keyed in 356.
365 x (24.02/165.83) = 52.869 which I would round to 52.9 g.
So I need to learn to type in the correct number. :-).
To determine the amount of carbon in 365 grams of dicarbon tetrachloride (CCl4), we need to calculate the molar mass of the compound, and then determine the ratio of carbon atoms in one mole of dicarbon tetrachloride.
Step 1: Calculate the molar mass of CCl4
To determine the molar mass, we need to sum up the atomic masses of all the atoms present in dicarbon tetrachloride. The atomic masses are found on the periodic table.
- Carbon (C) atomic mass = 12.01 g/mol
- Chlorine (Cl) atomic mass = 35.45 g/mol
Since there are four chlorine atoms in the compound, we multiply the atomic mass of chlorine by 4.
Molar mass of CCl4 = (2 × Carbon atomic mass) + (4 × Chlorine atomic mass)
Molar mass of CCl4 = (2 × 12.01 g/mol) + (4 × 35.45 g/mol)
Molar mass of CCl4 = 24.02 g/mol + 141.80 g/mol
Molar mass of CCl4 = 165.82 g/mol
Step 2: Calculate moles of CCl4
To calculate the number of moles in 365 grams of CCl4, divide the given mass by the molar mass.
Moles = Mass / Molar Mass
Moles = 365 g / 165.82 g/mol
Moles ≈ 2.20 mol
Step 3: Determine the number of carbon atoms
Each molecule of CCl4 contains 2 carbon atoms, so we multiply the moles of CCl4 by the number of carbon atoms per mole.
Number of carbon atoms = Moles of CCl4 × Number of carbon atoms in 1 mole
Number of carbon atoms = 2.20 mol × 2
Number of carbon atoms = 4.40 atoms
Therefore, there are approximately 4.40 carbon atoms in 365 grams of dicarbon tetrachloride.
