1. H2 + Cl2 => 2HCl
71kg Cl2.................2*36,5kg HCl
x kg Cl2...................116,8kg HCl
x=71*116,8/73=113,6kg Cl2
n(eta)=mp/mt*100 = 113,6/142*100 = Calculeaza !!
2. NH3 + HNO3 => NH4(NO3)
1 kmol NH3..................1 kmol NH4(NO3)
x=8 kmoli NH3.............8 kmoli NH4(NO3)
n(eta)=np/nt*100 = 8/10*100 = Calculeaza !!
3. H2O => H2 + 1/2O2
18g H2O................2g H2
90g H2O...............xg H2
x=2*90/18=10g H2 (mt)
n(eta) = mp/mt*100 => mp=n*mt/100=70*10/100 = Calculeaza !!
