Determine the solubility of X at different temperatures and plot a solubility curve.

Here are the solutions for the questions based on the provided image.

1. i) Determine the solubility of X at different temperatures and plot a solubility curve.

Step 1: Calculate the solubility of solid X for each volume of distilled water used.
The mass of solid X is 4.5 g. The density of water is approximately 1 g/$\text{cm}^3$, so the mass of water in grams is equal to its volume in $\text{cm}^3$.
Solubility is calculated as:

$$\text{Solubility (g/100g H}_2\text{O)} = \frac{\text{Mass of X (g)}}{\text{Mass of water (g)}} \times 100$$

Using the
