Asample of c3h8 has 8.08 × 1024 h atoms.

how many carbon atoms does the sample contain?

what is the total mass of the sample?

of carbon in the sample.

73.7960 grams is the total mass of the sample.

Explanation:

Compound =

Total numbers of hydrogen atoms in a compound = atoms

In one molecule of compound there are 8 hydrogen atoms.

Then x number of molecules of compound having hydrogen atoms.

In one molecule of compound there are 3 carbon atoms.

Then of given compound will have :

of carbon

of carbon in the sample.

Moles of given compounds = n

n = 1.6771 moles

Mass of 1.6771 moles of given compound:

73.7960 grams is the total mass of the sample.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
