student is investigating which type of sugar would dissolve fastest in hot tea- a sugar cube or granulated sugar. Which hypothesis should the student use for their investigation?

A.
It doesn't really matter. Both of them are sugar with the same chemical formula.

B.
Granulated sugar has more surface area than sugar cubes and will dissolve faster.

C.
Granulated sugar has less surface area than sugar cubes and will dissolve faster.

D.
Cubes have more surface area and will dissolve faster.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
