Had a lab few days ago and a question was presented: [q]Some people claim that women possess better color vision than men. Suppose ths is true. Two people perform this experiment and their results are as follows: Student1: Acetic Acid Concentration - 4.5% Student2: Acetic Acid Concentration - 4.8% Based on the gender claim which student is male and which is female? Explain your reasoning.[/q] :uhh: I am not exactly sure how to answer it. Can anyone help? :uhh: Second: I have the following results from my experiment after three trials: Mass of Erlenmeyer flask=A, Mass of flask and vinegar=B, mass of vinegar=C, initial volume of buret=D, final volume of buret=E, volume of NaOH delivered=F, and concentration of NaOH (mol/L) on bottle=G. I am asked to find Mass % of undiluted acetic acid and average mass % of undiluted acetic acid. We weren't given any formulas on how to determine this. Does anyone know what I would do in this case?
