(a) State the law of conservation of mass
(b) What mass of silver nitrate will react with 5.85 g of sodium chloride to produce 14-35 g of silver chloride and 8-5 g of sodium nitrate if the law of conservation of mass is true?

Explanation

(a) For answer, consult section 3.1
(b) The chemical reaction leading to products is :
Silver nitrate + Sodium cholride `to` Sliverr chloride + Sodium nitrate
Mass of reactants `=x g + 5.85 g`
Mass of products `= 14.35 g + 8.5 g`
According to law of conservation of mass
Mass of reactions = Mass of prdocuts
`(x + 5.85) g = (14.35 + 8.5 ) g`
` x = ( 22.85 - 5.85) g = 17.0g`
