Răspuns:
MH2=2×1=2g/mol
MO2=2×16=32g/mol
MH2O=2×1+16=18g/mol
nH2O=m/M=3600/18=200moli
2moli........1mol.....2moli
2H2 + O2 → 2H2O
xmoli........ymoli.......200moli
x=200×2/2=200moli H2
y=200×1/2=100moli O2
2×2g......32g........2×18g
2H2 + O2 → 2H2O
zg..................tg.........3600g
z=3600×2×2/2×18=400gH2
t=3600×32/2×18=3200gO2
