Ce cantitate de gaz se obtine prin arderea a 150 g de carbune de P=80%?
 \frac{12g}{\frac{C}{120g} } + O2=   \frac{44g}{\frac{CO2}{x} } 

 \frac{12}{20}=  \frac{44}{x} => x=  \frac{120x44}{12}=440gCO2
P=80%
mt=150g
 \frac{P}{100} = \frac{mp}{mt} => mp= \frac{Pxmt}{100} =120g Carbune  pur
Sper ca te-am ajutat.
