A sample of propane, C3H8, contains 12.2 moles of carbon atoms. How many total moles of atoms does the sample contain?

H = 8/3 *12.2 = 32.5

12.2 + 32.5 = 44.7

Well, let me calculate that for you. Since each molecule of propane contains 3 carbon atoms and 8 hydrogen atoms, we can determine the total number of moles of atoms in the sample. If you have 12.2 moles of carbon atoms, and each molecule of propane contains 3 carbon atoms, that means you have 12.2 / 3 = 4.07 moles of propane molecules.

Each propane molecule also contains 8 hydrogen atoms, so if you multiply the number of propane molecules (4.07 moles) by the number of hydrogen atoms per molecule (8), you get 4.07 * 8 = 32.56 moles of hydrogen atoms.

To find the total number of moles of atoms, you simply add the number of moles of carbon atoms (12.2) to the number of moles of hydrogen atoms (32.56).

Therefore, the sample of propane contains a total of approximately 44.76 moles of atoms.

You know, that's a whole lot of moles. It must be a party in that sample!

To determine the total number of moles of atoms in the sample of propane, we need to first calculate the number of moles of hydrogen atoms.

Propane, C3H8, consists of 3 carbon atoms and 8 hydrogen atoms.

Given that there are 12.2 moles of carbon atoms, we know that there are also 12.2 moles of propane molecules (since each propane molecule contains 1 carbon atom).

Next, we can calculate the number of moles of hydrogen atoms:

Since there are 8 hydrogen atoms in each propane molecule, the number of moles of hydrogen atoms will be:

8 hydrogen atoms/molecule * 12.2 moles of propane = 97.6 moles of hydrogen atoms

Now, to find the total moles of atoms in the sample, we add the moles of carbon atoms (12.2) to the moles of hydrogen atoms (97.6):

Total moles of atoms = Moles of carbon atoms + Moles of hydrogen atoms
= 12.2 mol + 97.6 mol
= 109.8 moles

Therefore, the sample of propane containing 12.2 moles of carbon atoms contains a total of 109.8 moles of atoms.

To find out how many total moles of atoms the sample of propane contains, we need to determine the number of moles of hydrogen atoms in the sample.

The molecular formula of propane, C3H8, tells us that there are three carbon atoms and eight hydrogen atoms in one molecule of propane.

Given that there are 12.2 moles of carbon atoms, we can relate this to the number of moles of propane molecules by using the mole ratio between carbon and propane. The mole ratio states that 1 mole of carbon atoms is present in 1 mole of propane molecules.

Therefore, the number of moles of propane molecules is also 12.2 moles.

Since there are 3 carbon atoms in each propane molecule, we multiply the number of moles of propane molecules by 3 to find the number of moles of carbon atoms:
12.2 moles C3H8 × 3 moles C/1 mole C3H8 = 36.6 moles of carbon atoms

Now, the total moles of atoms in the sample can be calculated by adding up the moles of carbon atoms and moles of hydrogen atoms:
Total moles of atoms = moles of carbon atoms + moles of hydrogen atoms

Since there are 8 hydrogen atoms in each propane molecule, we can calculate the moles of hydrogen atoms:
12.2 moles C3H8 × 8 moles H/1 mole C3H8 = 97.6 moles of hydrogen atoms

Therefore, the total moles of atoms in the sample is:
36.6 moles of carbon atoms + 97.6 moles of hydrogen atoms = 134.2 moles of total atoms.

So, the sample of propane contains a total of 134.2 moles of atoms.
