3) A student found that his titration had taken 10.00 mL of 0.1002 M NaOH to titrate 0.132 g of aspirin. Calculate his percent purity. Give a possible explanation of what might have affected his percent purity. 4) The NaOH solution is standardized with KHP in part 1 of this lab. If about 0.8 grams of KHP (MW 204.23 g/mol) is titrated with approximately 0.1 M NaOH, what is the approximate volume (mL) of NaOH required to reach the endpoint? Show your calculation below. Write this value in the box located in the procedure section for Part 1. 12
