QUESTION 4 An analyst incorrectly used the USP Karl Fischer titration, Method 1a to analyse 2g of the drug Cathinone for % H2O. H H If all the ketone within the drug reacted with methanol to produce water, what volume (mL) of water was produced in the ketal formation? Submit your answer (numbers only) to 2 decimal places. Hint: Consult video/ slides on side reactions of ketones. Given: Molecular wt of Cathinone = 149.193 g/mol H2O mol wt. = 18.02 g/mol density of H2O = 1.000 g/mL
