Vm=22,4 l/mol
M,cloura de etil= 64,5g/mol
M,etilamina=45g/mol M,dieilamina=73g/mol M,trieilamina= 101g/mol
Explicație:
CH3-CH2Cl + NH3---> CH3-CH2-NH2+HCl ori 3a moli
2CH3-CH2Cl +NH3---> (CH3-CH2)2NH + 2HCL ori 2a
3CH3-CH2Cl+NH3---> (CH3-CH2)3N + 3HCl ori 1a
total moli clorura de etil: niu=3a+4a+3a=10a
total moli NH3 :niu= 3a+2a+1a= 6a
masa de amine
m= a(3x45+2x73+101)=423----->a=1,107mol
masa de clorura de etil m=niuxM=- 10x1,107x64,5g=714g
volumul de amoniax V= niuxVm= 6x1,107x22,4 l=148,8 l
