The balanced chemical equation for this reaction is:
NaCl + AgNO3 → AgCl + NaNO3
From the equation, we can see that 1 mole of NaCl reacts with 1 mole of AgNO3 to produce 1 mole of AgCl.
To find the moles of NaCl and AgNO3 in the given solutions, we'll use the formula:
moles = concentration (M) x volume (L)
For the NaCl solution:
Moles of NaCl = concentration of NaCl x volume of NaCl solution
= (4.63 x 10^(-2) M) x (24.8 mL / 1000 mL/L)
= 0.01144 moles
For the AgNO3 solution:
Moles of AgNO3 = concentration of AgNO3 x volume of AgNO3 solution
= (3.67 x 10^(-2) M) x (30.0 mL / 1000 mL/L)
= 0.011 moles
Since the reaction between NaCl and AgNO3 is 1:1, the moles of AgCl formed will be equal to the limiting reactant, which is NaCl in this case. Therefore, the moles of AgCl formed will also be 0.011 moles.
To find the mass of AgCl precipitate formed, we'll use its molar mass, which is 143.32 g/mol. Using the formula:
mass = moles x molar mass
Mass of AgCl = 0.011 moles x 143.32 g/mol
= 1.576 g
Therefore, the mass of AgCl precipitate that forms is 1.576 grams.
