A sample of propane C3H8 contains 13.5 moles of carbon atoms how many total moles of atoms does the sample contain?

13.5 mols C X(1 m C3H8/ 3m C)=4.5 m c3h8

4.5 miles c3h8 x 11 atoms in c3h8= 49.5 moles of atoms

How many moles of carbon atoms are present in 4 moles of C3H8?

Well, if you have 13.5 moles of carbon atoms in the propane, you can't just leave out the poor hydrogen atoms! They deserve some love too! So, let's not forget the 8 moles of hydrogen atoms in the C3H8 formula.

To find the total number of moles of atoms in the sample, we add the moles of carbon and the moles of hydrogen together.

So, 13.5 moles of carbon atoms + 8 moles of hydrogen atoms = 21.5 moles of atoms in total!

Don't forget to give each atom a high-five for their contribution!

To determine the total number of moles of atoms in a sample of propane (C3H8), we need to calculate the moles of hydrogen atoms in the sample.

Propane (C3H8) consists of 3 carbon atoms (C) and 8 hydrogen atoms (H).

Given that the sample contains 13.5 moles of carbon atoms (C), we can assume that there are also 13.5 moles of propane (since every molecule of propane contains 3 carbon atoms).

To calculate the moles of hydrogen atoms (H), we multiply the moles of propane by the ratio of hydrogen atoms to propane molecules.

The ratio of hydrogen atoms to propane molecules is 8:1. This means there are 8 hydrogen atoms for every 1 propane molecule.

So, the number of moles of hydrogen atoms is calculated as follows:

moles of hydrogen atoms = moles of propane * (8 moles of H / 1 mole of propane)
moles of hydrogen atoms = 13.5 moles * (8 moles of H / 1 mole of propane)

moles of hydrogen atoms = 13.5 moles * 8
moles of hydrogen atoms = 108 moles

Therefore, the sample of propane (C3H8) contains a total of 13.5 moles of carbon atoms and 108 moles of hydrogen atoms.

To get the total number of moles of atoms in the sample, we add the moles of carbon atoms to the moles of hydrogen atoms:

Total moles of atoms = moles of carbon atoms + moles of hydrogen atoms
Total moles of atoms = 13.5 moles + 108 moles
Total moles of atoms = 121.5 moles

So, the sample of propane C3H8 contains a total of 121.5 moles of atoms.
