Atablespoon of sugar is added to a container of sugar water, and the tablespoon of sugar sinks to the bottom without dissolving. this situation is a) unsaturated. b) unable to determined due to a lack of information. c) saturated. d) supersaturated. the measure of the percent volume of a given solution will always be the same as its measure of percent mass. true or false explain answers : )

A0.10 m aqueous solution of sodium sulfate is a better conductor of electricity than a 0.10 m aqueous solution of sodium chloride. which of the following best explains this observation? (a) sodium sulfate is more soluble in water than sodium chloride. (b) sodium sulfate has a higher molar mass than sodium chloride. (c) to prepare a given volume of 0.10 m solution, the mass of sodium sulfate needed is more than twice the mass of sodium chloride needed. (d) more moles of ions are present in a given volume of 0.10 m sodium sulfate than in the same volume of 0.10 m sodium chloride. (e) the degree of dissociation of sodium sulfate in solution is significantly greater than that of sodium chloride.
