Question

Cati litri de CO2 se obtin prin arderea a 36,132 x 10 la 22 atomi de carbon?

Answer 1

Notam cu "a "=nr. de moli de C ce intra in reactie=>
=>nr. atomi C= a* 6,023×10^23=>36,123×10^22= a* 6,023×10^23=>
=> a=36,123×10^22/6,023×10^23=>a=36,123×10^22/6,023×10*10^22=>
=>a=36,123×10^22/6,023×10×10^22=>
=>a=36,123×10^22/60,23×10^22=>
=>a=0,6 moli C

0,6 moli              b l
C           + O2 = CO2
1 mol                 1 mol
                          1×22,4=22,4 l

0,6/1=b/22,4=>b=0,6×22,4=>b=13,44 l CO2
