Question

Dau coroana, urgentttt ‼️
CH3-CH2-CH(NH2)-COOH calculati compozitia procentuala, raportul maselor si raportul atomic.

Answer 1

Răspuns:

Bună,

M compus=12×4+9+14+16×2=93g/mol

93 g compus...48 g C...9 g H...14 g N...32 g O

100g compus...a..............b..........c............d

a=51,61%C

b=9,67%H

c=15,05%N

d=34,40%O

r. masic-C:H:N:O=48:9:14:32

r. atomic-C:H:N:O=4:9:1:2

Sper sa iti folosească!
