Răspuns:
amestecul este : a mol CaCL2 + b mol CaO
M,CaCL2= 111g/mol nu contine O
M,CaO=56g/mol; 1molCaO contine 1molO, adica 16g
100g amstec.........14,3gO
111a+56b..................16b
1600b= 1587a+800b
800b= 1587a--> b= 2a(rotunjit)
m,amestec= 111g+112g= 223g\
223g amestec..........111g CaCL2.........112gCaO
100g.........................................x............................y
x=49,8%CaCl2
y=50,2%CaO
