Question

Calculeaza compozitia procentuala pentru SO3 si H2CO3

Answer 1

Răspuns:

Explicație:

SO3

M= 32 + 3.16=80-------> 80g/moli

80g SO3---------32g S--------48g o

100g-----------------x---------------y

x= 100 . 32 : 80=40% S

y= 100 . 48 : 80=60% O

H2CO3

M= 2 +12 +3 . 16 =62-------> 62g/moli

62g H2CO3---------2g H --------12gC---------48 gO

100g-----------------------x--------------y----------------z

x= 100 . 2 : 62=3,23% H

y= 100 . 12 : 62=19,35% C

z= 100 . 48  : 62 =77,42% O
