A 30.0g sample of ethane, C2H6 contains 6.02 molecules.?

Question

How would you calculate the number of H atoms in this sample?

Answer 1

6.02 molecules?! that's darn heavy ones! if you know the number of molecules (N) then the number of atoms is 8*N.. If you know mass then you can tell number of molecules... You don't need number of molecules AND mass.. ok, you may need if you have some heavy isotopes, lol.

Answer 2

Atomic weights: C=12 H=1 C2H6=30

So 30.0g ethane contains 6.02 x 10^23 molecules

Answer 3

they did no longer come to a call to party. in case you´re speaking approximately Oklahoma what occurred became that a mass of chilly air from Canada met a mass of warm air from the Gulf of Mexico in mid-central US by twist of destiny. Entropy skill from order to sickness. 2 a lot of air collide and grow to be chaotic, what do you think of?

Answer 4

c2h6 c is carbon it has 2 carbon atoms per molicule and 6 hydrogen atoms per molicule

6.02..........................................6.02
x 2 carbon molicules.............. x 6 hydrogen molicules
------- --------
12.04 carbon molicules + 36.12 hydrogen molicules = 48.52 total molicules
