A student performed a titration experiment to determine the molarity of a sodium hydroxide solution. 22.45 mL of a NaOH solution were required to reach the equivalence point when titrating 50.0 mL of a solution containing 2.4567 g of potassium hydrogen phthalate (KHC8H4O4). What is the concentration of the sodium hydroxide solution? a. 0.2406 M NaOH
b. 0.5358 M NaOH
c. 0.1094 M NaOH
d. 1.782 M NaOH
e. none of these

Astudent is trying to create a table that compares hypotheses, theories, and laws. hypothesis theory law do scientific researchers formulate it? yes yes yes does it explain why things happen? yes yes no yes yes yes is it used to make predictions? no yes yes which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?
