MNaOH=ANa+AO+AH=23+16+1=40g/mol
MHCl=AH+ACl=1+35,5=36,5g/mol
MNaCl=ANa+ACl=23+35,5=58,5g/mol
n=m/M=80/40=2 moli NaOH
NaOH + HCl = NaCl + H2O
a) 1mol NaOH........................58,5g NaCl
2 moli NaOH...........................x=Calculeaza !
b) 1mol NaOH..............1mol HCl
2 moli NaOH................2moli HCl
