1.7 g of AgNO_(3) dissolved in 100 g of water wire mixed with 0.585 g of NaCl dissolved in 100 g of water when 1.435 g of AgCl and 0.85 g of NaNO_(3) were formed. Justify that the data illustrates law of conservation of mass.

Answer»

Solution :Since water has not taken PART in the reaction, its mass (200 G) will count towards both SIDES
Mass of REACTANTS `= 1.7 + 0.585 + 200 = 202.285 g`
Mass of products `= 1.435 + 0.85 + 200 = 202.285 g`
`:.` Law of conservation of mass is verified.
