Answer

Explanation:

Step1: Determine solubility of NaCl at 100°C

From the graph, the solubility of NaCl at 100°C is 40 g salt/100 g H₂O.

Step2: Set up proportion for 600 mL

Assume density of water is 1 g/mL, so 600 mL of water is 600 g. Let $x$ be the mass of NaCl. The proportion is $\frac{40\ g}{100\ g}=\frac{x}{600\ g}$.

Step3: Solve the proportion

Cross - multiply: $100x = 40\times600$. Then $x=\frac{40\times600}{100}=240$ g.

Answer:

240 g
