How many atoms are in 1.14 mol of propane (C3H8)?
A. 7.55 x 1023 atoms
B. 7.77 x 1024 atoms
C. 7.55 x 1024 atoms
D. 7.55 x 1030 atoms
C
indeed
1 mol contains 6.02E23 molecules.
Convert 1.14 mol C3H8 to molecules.
Then molecules C3H8 x 11 = ?
its C your original answer
Yes, C. You must have punched the wrong button(s).
To find the number of atoms in 1.14 mol of propane (C3H8), we need to use Avogadro's number. Avogadro's number is approximately 6.022 x 10^23 atoms/mol.
First, we need to calculate the total number of moles of atoms in propane. In propane (C3H8), there are 3 carbon atoms and 8 hydrogen atoms.
Number of carbon atoms = 3
Number of hydrogen atoms = 8
Total number of atoms = Number of carbon atoms + Number of hydrogen atoms
Total number of atoms = (3 carbon atoms) + (8 hydrogen atoms)
Total number of atoms = 11 atoms
Next, we calculate the number of moles of atoms in 1.14 mol of propane:
Number of moles of atoms = Total number of atoms / Avogadro's number
Number of moles of atoms = 11 atoms / (6.022 x 10^23 atoms/mol)
Number of moles of atoms = 1.82 x 10^-23 mol
Therefore, 1.14 mol of propane (C3H8) contains 1.82 x 10^-23 mol of atoms.
However, we need to convert this to a whole number, so we multiply by a suitable factor:
(1.82 x 10^-23 mol) x (6.022 x 10^23 atoms/mol) = 1.09444 x 10^1 atoms
So, there are approximately 1.09444 x 10^1 atoms in 1.14 mol of propane.
Now, to find the answer choice that corresponds to this value:
A. 7.55 x 10^23 atoms - This is too large.
B. 7.77 x 10^24 atoms - This is also too large.
C. 7.55 x 10^24 atoms - This is still too large.
D. 7.55 x 10^30 atoms - This is too large.
None of the answer choices match the calculated value. Therefore, none of the answer choices are correct.
