miu Ca(OH)2= 74g/mol; miu HNO3=63g/mol
1mol.............2mol
Ca(OH)2+2HNO3= Ca(OH)2 +2H2O
74g............2x63g
x.................189g..............................calculeaza X!

74g...............126g
Ca(OH)2 + 2HNO3 ----> Ca(NO3)2 + 2H2O
x=111g.........189g
MCa(OH)2=74g/mol
MHNO3=63g/mol
imi cer scuze de greseala..
