A solution of Ba(OH) 2 was standardized against 0.1215 g of primary-standard-grade benzoic acid, C 6 H
Question:
A solution of Ba(OH)2 was standardized against 0.1215 g of primary-standard-grade benzoic acid, C6H5COOH (122.12 g/mol). An end point was observed after addition of 43.25 mL of base.
(a) Calculate the molar concentration of the base.
(b) Calculate the standard deviation of the molar concentration if the standard deviation for the mass measurement was ±0.3 mg and that for the volume measurement was ±0.02 mL.
(c) Assuming an error of -0.3 mg in the mass measurement, calculate the absolute and relative systematic error in the molar concentration.

As an online tutor with over seven years of experience and a PhD in Education, I have had the opportunity to work with a wide range of students from diverse backgrounds. My experience in education has allowed me to develop a deep understanding of how students learn and the various approaches that can be used to facilitate their learning. I believe in creating a positive and inclusive learning environment that encourages students to ask questions and engage with the material. I work closely with my students to understand their individual learning styles, strengths, and challenges to tailor my approach accordingly. I also place a strong emphasis on building strong relationships with my students, which fosters trust and creates a supportive learning environment. Overall, my goal as an online tutor is to help students achieve their academic goals and develop a lifelong love of learning. I believe that education is a transformative experience that has the power to change lives, and I am committed to helping my students realize their full potential.
