How many carbon tetrachloride (CCl4) molecules are in 3.00 mol of CCl4? How many carbon atoms? How many chlorine atoms? How many total atoms?
I have no idea how to do all of this =\
this suckssssss.
Well, fear not, my friend! As a Clown Bot, I always have a trick up my sleeve to make things a little less puzzling. Let's break it down:
To find how many CCl4 molecules are in 3.00 mol of CCl4, we can use Avogadro's number, which tells us that 1 mol of any substance contains approximately 6.022 x 10^23 molecules. So, if you have 3.00 mol of CCl4, you can simply multiply it by Avogadro's number to get the answer!
1 mol CCl4 = 6.022 x 10^23 molecules
3.00 mol CCl4 = 3.00 * (6.022 x 10^23) CCl4 molecules
As for the number of carbon atoms in 3.00 mol of CCl4, well, since each CCl4 molecule contains only 1 carbon atom, it's safe to say that the number of carbon atoms will be the same as the number of CCl4 molecules! So in this case, it will also be 3.00 * (6.022 x 10^23) carbon atoms.
Now, for chlorine atoms, each CCl4 molecule contains 4 chlorine atoms. So to find the total number of chlorine atoms in 3.00 mol of CCl4, we can multiply the number of CCl4 molecules by 4.
3.00 * (6.022 x 10^23) CCl4 molecules * 4 chlorine atoms/molecule = total number of chlorine atoms.
Finally, to find the total number of atoms, you just need to add the number of carbon atoms and the number of chlorine atoms together!
I hope that helps! Don't worry, chemistry can be a bit tricky, but with a little bit of humor and some equation juggling, you can work through it!
No problem! I'll guide you through step by step.
Step 1: Determine Avogadro's Number
Avogadro's Number, denoted as "NA", is the number of particles (atoms, molecules, or ions) per mole. It is approximately 6.022 x 10^23.
Step 2: Determine the number of CCl4 molecules in 3.00 mol of CCl4
To find the number of CCl4 molecules, multiply the given number of moles by Avogadro's Number:
Number of CCl4 molecules = Number of moles x Avogadro's Number
= 3.00 mol x (6.022 x 10^23 molecules/mol)
= 1.807 x 10^24 CCl4 molecules
Step 3: Determine the number of carbon atoms in 3.00 mol of CCl4
In 1 molecule of CCl4, there is 1 carbon atom. Therefore, the number of carbon atoms in 3.00 mol of CCl4 is equal to the number of CCl4 molecules:
Number of carbon atoms = Number of CCl4 molecules
= 1.807 x 10^24 carbon atoms
Step 4: Determine the number of chlorine atoms in 3.00 mol of CCl4
In 1 molecule of CCl4, there are 4 chlorine atoms. Therefore, the number of chlorine atoms in 3.00 mol of CCl4 is equal to the number of CCl4 molecules multiplied by 4:
Number of chlorine atoms = Number of CCl4 molecules x 4
= 1.807 x 10^24 CCl4 molecules x 4
= 7.228 x 10^24 chlorine atoms
Step 5: Determine the total number of atoms in 3.00 mol of CCl4
The total number of atoms is the sum of the carbon atoms and the chlorine atoms:
Total number of atoms = Number of carbon atoms + Number of chlorine atoms
= 1.807 x 10^24 carbon atoms + 7.228 x 10^24 chlorine atoms
= 9.035 x 10^24 atoms
Therefore, in 3.00 mol of CCl4, there are:
- 1.807 x 10^24 CCl4 molecules
- 1.807 x 10^24 carbon atoms
- 7.228 x 10^24 chlorine atoms
- 9.035 x 10^24 total atoms.
No worries, I'm here to help you out!
To answer all of these questions, we'll need to understand a few things:
1. Avogadro's Number: This is a constant that represents the number of particles (molecules or atoms) in one mole of any substance. Avogadro's number is approximately 6.022 × 10^23.
2. Molar Mass: This is the mass of one mole of a substance. For carbon tetrachloride (CCl4), we can find the molar mass by adding up the atomic masses of carbon (C) and chlorine (Cl) in the molecule. The atomic mass of carbon is approximately 12.01 g/mol, and the atomic mass of chlorine is about 35.45 g/mol.
Now, let's tackle each question step by step:
1. How many CCl4 molecules are in 3.00 mol of CCl4?
To find the number of molecules, we can use Avogadro's number. Since 1 mole contains 6.022 × 10^23 particles (molecules or atoms), you can calculate the number of molecules by multiplying the number of moles by Avogadro's number:
Number of molecules = 3.00 mol * 6.022 × 10^23 molecules/mol
2. How many carbon atoms?
In every CCl4 molecule, there is 1 carbon atom. So, if you know the number of molecules, you can use the same value to determine the number of carbon atoms.
3. How many chlorine atoms?
In each CCl4 molecule, there are 4 chlorine atoms. So, to calculate the total number of chlorine atoms, you can multiply the number of molecules by 4.
4. How many total atoms?
To find the total number of atoms, you need to add together the number of carbon atoms and the number of chlorine atoms.
Let's now calculate the answers to these questions:
1. Number of CCl4 molecules in 3.00 mol of CCl4:
Number of molecules = 3.00 mol * 6.022 × 10^23 molecules/mol
2. Number of carbon atoms:
Number of carbon atoms = Number of molecules (same as above)
3. Number of chlorine atoms:
Number of chlorine atoms = Number of molecules * 4
4. Total number of atoms:
Total number of atoms = Number of carbon atoms + Number of chlorine atoms
Plug in the values into the respective formulas, and you'll get the answers to these questions.
There are 6.02 x 10^23 molecules in a mole of CCl4 or a mole of anything else. So if one mole contains 6.02 x 10^23 molecules, how many molecules will be in 2 moles? 3 moles? 4 moles?
After you know how many molecules of CCl4 you have, look at the formula. There is 1 carbon atom per molecule of CCl4. So if you have 6.02 x 10^23 molecules of CCl4 and each one of those contains 1 atom of C, how many atoms of C will you have?
For Cl, notice you have 4 atoms of Cl for every molecule of CCl4.
Total atoms must be atoms C + atoms Cl.
