-calculez masa molara M din nr.moli ,n=V/Vo=m/M
0,1/M= 0,032 l/22,4 l/mol---> M=70g/mol
-deduc formula moleculara
la 0,7g compus.......0,05molCO2=0,05molC
70g.........................n=5molC
LA 0,7g compus......0,05molH20=0,1molH
70G........................................10molH---> C5H10-PENTENA
1 pentena C=C-C-C-C
2 pentena C-C=C-C-C cu izomeri CIS ,TRANS
2metil 1 butena C=C(CH3)-C-C
2metil 2 butena C-C(CH3)=C-C completeaza cu H !!!!!!
1mol 7,5mol
C5H1O+15/2O1---> 5CO2+5H2O
3mol............22,5mol----> V= 22,5molx22,4l/mol
aerul are 20%O2-> Vaer=5V,o2--> V aer= 5x22,5x22,4 l calculeaza !!!!
