Question

which statement best compares the solubility of these substances at 40°c?
a substance c has 30 g of solute.
b substance b has more solute dissolved than substance c.
c substance c has more solute dissolved than substance b.
d substance d has the greatest solubility.

Explanation:

Step1: Analizar la gráfica

Observar la solubilidad de cada sustancia a \(40^{\circ}C\).

Step2: Comparar solubilidades

• Sustancia A: Aproximadamente \(80\) g en \(100\) g de agua.
• Sustancia B: Aproximadamente \(40\) g en \(100\) g de agua.
• Sustancia C: Aproximadamente \(10\) g en \(100\) g de agua.
• Sustancia D: Aproximadamente \(90\) g en \(100\) g de agua.

Answer:

D. Substance D has the greatest solubility.
