Answer: 1.35x 10²³ molecules FeCl3
Explanation: First find the number of moles for FeCl3 using its molar mass which is equal to 162.2 g FeCl3
Convert moles of FeCl3 to molecules by using the Avogadro's number.
Moles of titrant are lost in the calculation in redox titration.
"The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration.
The equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, is to be detected by the titration. The stoichiometry of the reaction determines how many reactants have been combined at the equivalence point.
Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. In the realm of analytical chemistry, titration is a crucial technique.

Answer:
i believe it is all but c
Explanation:
Explanation:
Given parameters:
Mass of aspirin = 0.45g
Mass of C = 0.27g
Mass of H = 0.02g
Mass of O = 0.16g
Unknown:
Mass percentage of the constituents = ?
Solution:
To find the mass percent, ensure that sum of the mass of the elements add up to the that of the given mass of aspirin
Total mass = 0.27 + 0.02 + 0.16 = 0.45g
Now express each of the given percentages to that of the total one.
mass percent of C =
x 100 = 60%
mass percent of H =
x 100 = 4.4%
mass percent of O =
x 100 = 36%
