-date de care am nevoie
M(miu)= (23gNa+16gO+1gH)/mol= 40g/mol NaOH
M= (23gNa +35,5gCl)/mol= 58,5g/molNaCl
-calculez masa de sare,clorura de sodiu, din ecuatia:
1mol ......................1mol
NaOH + HCl----> NaCl + H2O
40g..........................58,5g
160g............................x=.......................calculeaza !!!!
