A sample of propane, C3H8, contains 10.0 moles of carbon atoms. How many total moles of atoms does the sample contain? Express the total number of moles of carbon and hydrogen numerically.

10moles/3=TN/11

Totalmoles=110/3
total carbon=10
total H atoms=80/3

To determine the total number of moles of atoms in the propane sample, we need to consider the molecular formula of propane, which is C3H8.

From the formula, we can see that for every molecule of propane, there are 3 carbon atoms (C3) and 8 hydrogen atoms (H8).

Given that the sample contains 10.0 moles of carbon atoms, this means that there are 10.0 moles of C3 groups in the sample.

Since each C3 group consists of 3 carbon atoms, we can calculate the total number of moles of carbon atoms in the sample by multiplying the number of moles of C3 groups by the number of carbon atoms per C3 group.

Total moles of carbon = 10.0 moles C3 groups × 3 carbon atoms/molecule = 30.0 moles of carbon atoms

Similarly, since each propane molecule consists of 8 hydrogen atoms (H8), the total number of moles of hydrogen atoms can be calculated by multiplying the number of moles of propane molecules by the number of hydrogen atoms per molecule.

Total moles of hydrogen = 10.0 moles of propane × 8 hydrogen atoms/molecule = 80.0 moles of hydrogen atoms

Therefore, the total number of moles of atoms in the sample is 30.0 moles of carbon and 80.0 moles of hydrogen.

To find the total number of moles of atoms in the propane sample, we need to consider both carbon and hydrogen atoms.

First, let's determine the number of moles of hydrogen atoms. Propane has a chemical formula of C3H8, which means that there are 8 hydrogen atoms in each molecule. Since we have 10.0 moles of carbon atoms provided, we can assume that we also have 10.0 moles of propane molecules.

To calculate the moles of hydrogen, we can use the mole ratio between carbon and hydrogen atoms in propane, which is 1:8. This means that for every 1 mole of carbon atoms, there are 8 moles of hydrogen atoms.

So, we can calculate the moles of hydrogen atoms by multiplying the number of moles of carbon atoms by the mole ratio:

10.0 moles of carbon atoms × 8 moles of hydrogen atoms/mole of carbon atoms = 80.0 moles of hydrogen atoms

Therefore, the sample of propane contains 10.0 moles of carbon atoms and 80.0 moles of hydrogen atoms, giving a total of:

10.0 moles of carbon atoms + 80.0 moles of hydrogen atoms = 90.0 moles of atoms in total.
