Calculate the concentration of diluted solution A (NaOH) using the titre, t1. The calculation is: (0.0025 mol) / (0.0254 dm3).

You're doing great, Gobte! Let's finish these calculations.

Continuing from where we left off:

a) The concentration of diluted solution A using the titre, t$_1$.

Step 5: Complete the calculation for the concentration of diluted solution A (NaOH).

$$\text{Concentration of diluted Solution A} = \frac{0.0025 \text{ mol}}{0.0254 \text{ dm}^3}$$ $$\text{Concentration of diluted Solution A} = 0.098425... \text{ mol/dm}^3$$

Rounding to three significant figures:
