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?
