Răspuns:
-calculez masa si moli acid.stiind miuHCl=36,5g/mol
c=mdx100/ms---> md= 36,5x10/100g=3,65gHCl
niu=m./miu=3,65/36,5mol= 0,1molHCl
calculez moli si masa de sare NaCl, stiind miuNaCl= 58,5g/mol
1mol..........................1mol
HCl + NaOH----> NaCL + H2O
0,1mo.........................x
x= niu=0,1molNaCl
m=niuxmiu= 0,1x58,5g=5,85gNaCl
