niu,amoniac= V/Vm= 61,6 l/22,4 l/mol= 2,75mol
din ecuatia chimica NH3 +H2O=NH4OH, rezulta ca se obtin 2,75molNH4OH
m,NH40H= niuxM= 2,75gx35g/mol= 96,25g=md
ms= 97g
c=mdx100/ms= 96,25x100/97=........................calculeaza !!!
1mol...........1mol
NH4OH + HCl---> NH4Cl + H2O
35g............36,5g
96,25g.........x=100,37gHCl=md
20= 100,37x100/ms----> ms=502g
ro=m/v---> v= m/ro= 502g/1,1g/ml=......................calculeaza !!!!!
