NH3+HCl=NH4Cl
masa molara NH3=17g pe mol
m NH3=10*17g
m NH3=170g
ms HCl=730g
c=20g
md HCl=146g
facand inmultirea pe diagonala obtinem:2482=6205
inseamna ca avem NH3 in exces
notam m NH3=x
x=68g
m NH3 exces=102g
m NH4Cl=214g
masa molara NH4Cl=53,5
1 mol NH4Cl.................53,5g
a moli NH4Cl...............214g
a=4
m apa=ms-md
m apa=584g
ms final =m apa+m NH4Cl
ms final=798g
