To solve this problem, let's break it down step by step.
Step 1: Calculating the average titre value
To calculate the average titre value, you need to add up all the titre values and divide by the number of readings. In this case, you have three readings.
Average titre value = (33.50 + 33.60 + 33.70) / 3 = 100.8 / 3 = 33.6
So, the average titre value is 33.6.
Step 2: Calculating the concentration of B in mol/dm³
To calculate the concentration of B, we can use the balanced equation between HCl and KOH: HCl + KOH -> H2O + KCl.
From the equation, it is clear that the mole ratio between HCl and KOH is 1:1. Therefore, the concentration of B (KOH) can be calculated using the average titre value and the concentration of A (HCl).
Concentration of B (mol/dm³) = Concentration of A (mol/dm³) * Average Titre Value
Since the concentration of A (HCl) is not provided in the question, we cannot solve for the concentration of B (KOH) or the concentration of A (HCl) just yet. We need additional information.
Step 3: Calculating the concentration of A in mol/dm³
Similarly, to calculate the concentration of A, we use the same equation and mole ratio.
Concentration of A (mol/dm³) = Concentration of B (mol/dm³) * Average Titre Value
Again, since we do not have the concentration of either A or B, we cannot solve this equation either.
Step 4: Calculating the concentration of A in g/dm³
To calculate the concentration of A in g/dm³, you will need the molar mass of A. Without this information, we cannot provide you with the answer.
In summary, the given information is incomplete, and we need either the concentration of A (HCl) or the molar mass of A to solve for the concentrations of A and B.
