Answer:
We know the equation BaCl2 + Na2SO4 --> BaSO4 + 2NaCl
on LHS we have 137 + (35.5)*2 + (23)*2 + 32 + (16) * 4 = 350
on RHS we have 137+ 32 + (16)*4 + (23 + 35.5) * 2 = 350
Therefore we see mass is neither created nor destroyed.
Also if equation is balenced, the weight is also balanced.
The equation is from 10th chemistry, if you are below 10th you might not know it.
