What is the molarity of a solution that has 0.030 mil of NaCl dissolved in 1.2 L solution?

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.

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.

Acertain reaction has a activation energy of 54.0 kj/mol. as the temperature is increased from 22c to a higher temperature, the rate constant increases by a factor of 7.00. calculate the higher temperature. c (report only numerical answer)
