Question

Ce cantitate de carbon e cuprinsa in 88 g dioxid de carbon.

Answer 1

 
 CO2
Se calculeaza masa moleculara =MCO2=12 +2.16=44
Daca in 44 g CO2 se afla 12 g C atunci in 88g CO2 se afla Xg C

44gCO2---------12 g C
88g CO2--------X g CO2
X=88.12 :44=24 gC

Answer 2

MCO₂ = 12+(2*16)= 44g/mol
 44gCO₂.............................12gC
88gCO₂...................................X

X= 88*12/44=24gC
