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?
To determine the mass of silver nitrate required for the reaction, we need to use the law of conservation of mass. This law states that mass is neither created nor destroyed during a chemical reaction. Therefore, the total mass of the reactants should be equal to the total mass of the products.
Let's calculate the molar masses of the compounds involved:
- Sodium chloride (NaCl): 1 sodium atom (Na) + 1 chlorine atom (Cl) = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol
- Silver chloride (AgCl): 1 silver atom (Ag) + 1 chlorine atom (Cl) = 107.87 g/mol + 35.45 g/mol = 143.32 g/mol
- Sodium nitrate (NaNO3): 1 sodium atom (Na) + 1 nitrogen atom (N) + 3 oxygen atoms (O) = 22.99 g/mol + 14.01 g/mol + (3 × 16.00 g/mol) = 85.00 g/mol
Now, let's set up the equation to balance the reaction:
2AgNO3 + NaCl → 2AgCl + NaNO3
From the balanced equation, we can see that the molar ratio between AgNO3 and NaCl is 2:1. So, we need to find the molar mass of 1 mole of NaCl:
58.44 g/mol × 1 mol = 58.44 g
To find the mass of AgNO3 required, we can use the equation:
5.85 g NaCl × (1 mol NaCl / 58.44 g NaCl) × (2 mol AgNO3 / 1 mol NaCl) × (169.87 g AgNO3 / 1 mol AgNO3) = 9.71 g AgNO3
Therefore, approximately 9.71 grams of silver nitrate are required to react with 5.85 grams of sodium chloride and produce 14.35 grams of silver chloride and 8.5 grams of sodium nitrate.
To determine the mass of silver nitrate that will react with sodium chloride, we need to apply the law of conservation of mass. According to this law, the total mass of the reactants must be equal to the total mass of the products.
We are given:
Mass of sodium chloride (NaCl) = 5.85g
Mass of silver chloride (AgCl) = 14.35g
Mass of sodium nitrate (NaNO3) = 8.5g
To find the mass of silver nitrate (AgNO3), we need to subtract the mass of silver chloride and sodium nitrate (the products) from the mass of sodium chloride (the reactant).
Total mass of products = Mass of silver chloride + Mass of sodium nitrate
= 14.35g + 8.5g
= 22.85g
Mass of silver nitrate (AgNO3) = Mass of sodium chloride - Total mass of products
= 5.85g - 22.85g
= -17g
Upon calculating, we get a negative mass for silver nitrate, which indicates that the given data violates the law of conservation of mass. This implies that either the data is inaccurate or there might be an error in the measurements or calculations.
If the given data were accurate and the law of conservation of mass were followed, we would expect the mass of silver nitrate to be positive. In this case, we would need more information or revised data to calculate the mass of silver nitrate that would react with sodium chloride.
