Practice question
Question
When 1.0 g of urea (Molecular Weight = 60) is dissolved in 200 g of solvent S, the freezing point of S is lowered by 0.25 °C. When 1.5 g of a non-electrolyte Y is dissolved in 125 g of S, the freezing point of S is lowered by 0.20 °C. The molecular weight of Y is ___________.
Explanation
Evidence for core biological organization indicates structure-function relationships govern cellular processes. Option NAT aligns with this, as it integrates fundamental life science principles, reflecting standard interpretations in general biology. This mechanism is extensively documented and reinforced by experimental data across multiple model systems and textbook discussions.
