Asample of propane, c3h8, contains 15.5 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.

We have that the total number of moles of carbon and hydrogen numerically. is

X=57moles

From the question we are told

A sample of propane, C3H8, contains 15.5 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

Generally the equation for the number of Carbon  is mathematically given as

Since

H =8 in C3H8

Therefore

Therefore

the total number of moles of carbon and hydrogen numerically.

is

X=57moles

H = 41.3 mol H; Atoms = 56.8 mol

Explanation:

A molecule of propane contains eight atoms of H for every 3 atoms of C or 8 mol H atoms for every 3 mol C atoms.

∴

Total atoms = 15.5 mol C atoms + 41.3 mol H atoms = 56.8 mol atoms

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
