Unformatted text preview: Post-Lab Data Summary Note : some questions will display a variable like "nCount" or "SyInput" instead of an actual number in the data summary. Q# Question Text 4) Scoring Scheme: 3-3-2-1 Part I. How many mL of 6 M NaOH stock solution should be used to prepare the 1L of 0.15 M NaOH? Please enter your answer to a tenth of a mL, e.g. ,10.3 mL. mL of 6M NaOH = Your Answer: 25 You Scored 3 points out of 3 Possible 5) Scoring Scheme: 3-3-2-1 Part I. How many mL of 6 M HCl stock solution should be used to prepare the 1L of 0.20 M HCl? Please enter your answer to a tenth of a mL, e.g. 10.3 mL. mL of 6M HCl = Your Answer: 33.3 You Scored 3 points out of 3 Possible 6) Data Entry - No Scoring Part II. For each of your THREE ACCEPTABLE trials (not the cursory one) in standardizing your NaOH against KHP, enter the mass in grams of KHP for each of the three samples to one thousandth of a gram, e.g. 1.104g. Your Answer: 1.118 No Points Possible Your Answer: 1.099 No Points Possible Your Answer: 1.026 No Points Possible 7) Data Entry - No Scoring Part II.
