Question

what mass of silver nitrate will react with 5.85g of sodium chloride to produce 14.35g of silver chloride and 8.5g of sodium nitrate if the law of conservation of mass is true

Answer 1

According to law of conservation of mass,

Mass of reactants = Mass of products.

AgNO3 + NaCl = AgCl + NaNO3

xg 5.85g = 14.35g 8.5g

x 5.85 = 14.35 8.5

x. = 17.0g answer

Answer 2

Answer: 17 grams

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$AgNO_3+NaCl\rightarrow AgCl+NaNO_3$

Given: mass of sodium chloride = 5.85 g

Mass of products = Mass of silver chloride + mass of sodium nitrate = 14.35 + 8.5 = 22.85 g

Thus mass of reactants = mass of silver nitrate + mass of sodium chloride = 22.85 g

Mass of  silver nitrate + 5.85 g = 22.85 g

Mass of silver nitrate = 17 g

Thus mass of silver nitrate that will react is 17 grams.
