How many carbon atoms are contained in each of the following number of moles:
(a) 1.40 mol; (b) 5.70 mol?
What is #moles*Avagrodo's Number ?
There are 6.02E23 molecules in 1 mol of anything; therefore, there are 6.02E23 x 1.4 = ? molecules of your compound. You must know what compound you have (or the formula) before you can calculate the number of C atoms.
Oh, carbon atoms, the life of the party! Let's do some math together, shall we?
(a) 1.40 mol of carbon atoms. That's like having a carbon atom convention!
Now, just to refresh your memory, Avogadro's number tells us that there are approximately 6.022 x 10^23 atoms in a mole. So, all we have to do is multiply that by 1.40.
6.022 x 10^23 atoms/mol * 1.40 mol ≈ 8.431 x 10^23 carbon atoms.
(b) 5.70 mol of carbon atoms. That's even more carbon atoms than before! Time to break out the disco lights! Multiply Avogadro's number by 5.70.
6.022 x 10^23 atoms/mol * 5.70 mol ≈ 3.439 x 10^24 carbon atoms.
So, in summary:
(a) 1.40 mol contains approximately 8.431 x 10^23 carbon atoms.
(b) 5.70 mol contains approximately 3.439 x 10^24 carbon atoms.
Now you can throw an atomic party and invite all those carbon atoms! Just be sure to keep an eye on them, they can be quite mischievous. Enjoy!
To determine the number of carbon atoms in a given number of moles, we need to use Avogadro's number, which is approximately 6.022 × 10^23 atoms/mol.
(a) For 1.40 mol of carbon atoms:
Number of carbon atoms = Number of moles × Avogadro's number
Number of carbon atoms = 1.40 mol × (6.022 × 10^23 atoms/mol)
Number of carbon atoms = 8.43 × 10^23 atoms
Therefore, there are approximately 8.43 × 10^23 carbon atoms in 1.40 mol.
(b) For 5.70 mol of carbon atoms:
Number of carbon atoms = Number of moles × Avogadro's number
Number of carbon atoms = 5.70 mol × (6.022 × 10^23 atoms/mol)
Number of carbon atoms = 3.44 × 10^24 atoms
Therefore, there are approximately 3.44 × 10^24 carbon atoms in 5.70 mol.
