Ответ:
N = Na(число авогадро) * n
n(CH4) = m/M = 2000г/16г/моль=125моль
N (CH4)= 6*10^23 * 125 = 750*10^23 молекул.
n(C3H8) = 500/44=11моль
N(C3H8) = 6*10^23 * 11 = 66*10^23
n(C4H10) = 200/58=3моль
N(C4H10) = 6*10^23 * 3 =18*10^23

13. There are a million different jobs in music (who/which/that) don't involve performing professionally; it's a great business for that.

14. One obvious one is in teaching; you can go to college and become a professional music teacher either for schools or as a private tutor. Peripatetic teachers, ones (who/which/that) travel from school to school, are very popular just now.

15. Another suggestion is in music therapy. This can be helping people (who/which/that) have physical or mental disabilities to use music as a tool in co-ordination.

16. It can also help accident victims to re-use limbs (who/which/that) have been broken or to come to terms with trauma.

17. If you are into instruments, you can look at the art of making and repairing either modern instruments such as in piano tuning or by learning the skills to recreate old instruments. You'd probably need to talk to a museum (who/which/that) specialises in these instruments about what qualifications you'd need. In the same vein there is conservation work to be had by training to restore old instruments in museums or conserve old manuscripts.

18. For every person upfront enjoying the limelight there are about two hundred people backstage working in music. There are recording engineers, artist managements, artists, songwriters, and A&R (artist and repertoire - the people (who/which/that) discover new acts). In broadcasting there are music journalists, presenters, DJs and researchers.
