Homework Answers
For the most accurate approximation, we need to look for the data which has the greatest number of significant figures.
So, the answer is a.
25 has 2 significant figures and 2.00 has 3 significant figures. So, the result will have two significant figures in this case. In others, the least number of significant figures is one. So, the results will have only one significant figures.

Suppose 1.00 g of NaOH is used to prepare 250 mL of an NaOH solution. Compare the expected molarity of this solution to the actual average molarity you measured in the standardization. What do you notice? Do you think the results would have been more accurate if a different type of acid or base were used in the standardization? Why, or why not? There are many different primary standards that could be used in a standardization titration. What are the...
