Advance Study Assignment: Molar Mass of an Unknown Acid 1. 7.0 mL of 6.0 M NaOH are diluted with water to a volume of 400 mL. We are asked to find the molarity of the resulting solution. a. First find out how many moles of NaOH there are in 7.0 mL of 6.0 M NaOH. Use Equation 1. Note that the volume must be in liters. moles b. Since the total number of moles of NaOH is not changed on...
| A 0.458 g sample of a diprotic acid is dissolved in water and titrated with 0.170 M NaOH. What is the molar mass of the acid if 37.4 mL of the NaOH solution is required to neutralize the sample? Assume the volume of NaOH corresponds to the second equivalence point. molar mass: g/mol
Question 7 (2 points) A 2.070-g sample of a monoprotic acid was dissolved in water. It took 16.35 mL of a 0.4159 M NaOH to neutralize the acid. Calculate the molar mass of the acid. Provide your answer to two places after the decimal. No points for units. Your Answer: Answer units Hide hint for Question 7 The reaction stoichiometry between the monoprotic acid and NaOH is 1:1.
