A sample of propane, C3H8, contains 17.0 moles of carbon atoms. How many total moles of atoms does the sample contain

The answer is "62.33 mol atoms".

Explanation:

In the propane molecule, it  includes 8 atoms of Hydrogen for every 3 atoms of Carbon or 8 mol Hydrogen atoms for each of the 3 mol Carbon  atoms.

Total atoms = 17.0 mols of C atoms +45.33 mols of H atoms

                    =62.33 mol atoms

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
