Final answer:
Nitrous oxide is approximately 1.5 times more soluble in water than nitrogen, making option (b) the accurate choice.
Step-by-step explanation:
To answer the question regarding the solubility of nitrous oxide compared to nitrogen, we refer to the provided information. Although there is no direct experimental data given, based on the text about oxygen and nitrogen solubility, it can be inferred that solubility is largely dependent on intermolecular forces and other properties of the gas. Oxygen is mentioned as being twice as soluble in water compared to nitrogen.
However, an additional bit of common knowledge or research will tell us that nitrous oxide, N2O, is approximately 1.5 times more soluble in water than nitrogen, N2. Therefore, the correct response would be option (b), 1.5 times. This relates to Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the liquid.
