Question

1.7 gram of AGno3 dissolved in hundred gram of water when mixed with 0.5 85g if NaCl is dissolved in hundred gram of water wjem 1.437 gram of agcl and 0.85g gram of nano3 were formed justify that the data illustrate law of conservation of mass

Answer 1

1.7 gram AgNO3 (aq.) + 0.0585gram of NaCl (aq.) = 1.437 gram of AgCl (aq.) + 0.85 gram of NaNO3 (aq.)
Total mass of reactant = 1.7+0.585=2.285gram
Total mass of product = 1.437+0.85=2.287gram
Total mass of reactant approx = Total mass of product.
This reaction shows law of conservation of mass.
