A 0.656 g sample, initially at a temperature of 30 deg. C, of naphthalene was ignited in a bomb calorimeter. In a separate calibration experiment, a sample of 0.825 g sample of benzoic acid produced a temperature rise of 1.94 deg. C. Use this information to determine the final T in the naphthalene experiment.

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.
