what mass of silver nitrate will 5.85g of sodium chloride to produce 14.35g of silver chloride and 8.5g of silver nitrate if the law of conservation of mass is true??0
Answers
17 Grams
Given:
Mass of Sodium Chloride = 5.85 grams
Mass of Silver Chloride which is produced = 14.35 grams
Mass of Silver Nitrate which is produced = 8.5 grams
To Find:
Mass of Silver Nitrate if the law of conservation of mass is true.
Calculating:
The Equation in words
Silver Nitrate + Sodium Chloride -------------> Sodium Nitrate + Silver Chloride
This is a double displacement reaction.
AgNO3 + NaCl --------------> NaNO3 + AgCl
5.85 g 8.5 g 14.35 g
The law of conservation of mass tells us that the total number of reactants is equal to the total number of products.
In a chemical reaction the mass of the substances in reactant side is always equal to the mass of the substances in the product side.
Adding masses in the product side we get:
= 8.5 g + 14.35 g
= 22.85 grams
The mass of the reactant side = 5.85 grams
So to find the mass of Silver Nitrate the formula we are going to use:
= Mass of Product Side - Mass of Sodium Chloride
Substituting the values into this formula we get:
= 22.85 - 5.85
= 17 grams
Therefore, the mass of silver nitrate is 17 grams if the law of conservation of mass is true.
