Răspuns:

1.

1mol...........................1.mol.......2mol

CH3OH+3/2O2---> CO2+2H2O

5mol...........................x

x=niu= 5molCO2

V=niuxVm= 5molx22,4l/mol= 112 l

2.M,CH3OH= 32g/mol

   M,H2O= 18g/mol

1mol  CH3OH..........2molH2O   sau, in grame,

32g CH3OH..................2X18gH2O

X......................................3,6g

x= 3,2gCH3OH
