A 3-column table with 5 rows. Column 1 is unlabeled with entries A, B, C, D, E. Column 2 is labeled Temperature in degrees Celsius with entries 2.4, 21.5, 39.6, 55.6, 71.2. Column 3 is labeled Volume in cubic centimeters with entries 5.8, 5.8, 6.7, 6.9, 7.4.
A student collected the data shown above. Row may represent an error.
What might the student have done that caused this error? List all possible causes

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.
