m= 351kg NaCl ???????????
m,HCl =?
M(miu),HCl= (1gH +35,5gCl)/mol= 36,5g/mol
MNaCl= (23gNa+35,5gCl)/mol= 58,5g/mol
ecuatia reactiei este:
2mol........................................2mol
2NaCl + H2SO4---> Na2SO4 + 2HCl
2x58,5g..................................2x36,5g
351000g.................................x= m,HCl=.........calculeaza !!!!!!!
