Question) Answer the following questions.
![< Part A.: Standardization of KMnO4 solution >
Question) If the dispensed volume (mL) of Na2C2O4
= 26.27 mL, the dispensed volume (mL) of KMnO4 =
26.23 mL and [Na2C2O4] = 0.0531 M, determine
the molarity (M) of KMnO4.
1) In this case, your answer should be in scientific
notation (for example, 1.23*10^-1, not 0.123,) with
the correct number of significant figures. Also
follow the unit specified in each question. Do NOT
put its unit in your answer because its unit is shown
already in the questions.
2) It means students shouldn't include any letters or
text in the "Numeric answers", because otherwise
it'll be marked wrong even if the numbers are
correct.
