Answer: Option c. Solution A has a lower boiling point than solution B
Explanation:
For solution A, i = 1 means the solution is a non-electrolyte. This clearly indicates that solution A contains covalently bonded compound. Covalently bonded compounds have lower boiling when compared to those of the ionic.
For solution B, i = 2 means the compound is an electrolyte and it forms two ions. From this result, it is very clear that the compound in solution A is an ionic compound. Ionic compounds have higher boiling points than covalent compounds
Therefore, solution A will have a lower boiling point than solution B
Given that the rate of diffusion is 1 mm per 1 second. then the time it travels in 1 cm can be solve using the formula t = d / r where d is the distance r is the rate
So grams = mols*MolarMass. Here, MolarMass (MM) = 105.99g which can be found using the periodic table. mols is given to be 0.802. We can then plug in to get that it corresponds to 85.0g.
