MAgCl =108+35,5=143,5g/mol
MAgNO3=108+14+3x16=170g/mol
n=m/M=15/170=0,08moli AgNO3
2moli..........................2moli
2AgNO3 + BaCl2 → 2AgCl + Ba(NO3)2
0,08moli......................xmoli
x=0,08x2/2=calculeaza
calculam in grame
2x170g........................2x143,5g
2AgNO3 + BaCl2 → 2AgCl + Ba(NO3)2
15g...............................yg
y=15x2x1433,5/2x170=calculeaza
