Calculate the concentration of NaOH (Solution B) in mol dm⁻³ given that it contains 4.0 g of NaOH per dm³ of solution.

Here are the calculations for Question 1 (b) and the observations/inferences for Question 2 (a).

Question 1: Volumetric Analysis

(b) From your results and the information provided, calculate the:

(i) concentration of B in mol dm⁻³.

Step 1: Calculate the molar mass of NaOH.

$$\text{Molar mass of NaOH} = \text{Na} + \text{O} + \text{H} = 23 + 16 + 1 = 40 \text{ g/mol}$$

Step 2: Calculate the concentration of NaOH (Solution B).
Solution B contains 4.0 g of NaOH per dm³ of solution.
